Billboard’s March edition proclaims “Women are Dominating The Billboard Hot 100.” Women have indeed claimed more no.1 spots on Billboard’s 2019 charts already than they did for all of 2018.

Two years ago, Trevor Anderson also tracked how female-acts have increasingly claimed the No. 1 slot of Billboard’s Hot 100 over decades:

When it comes to streaming, Spotify and Apple Music have built their own top charts to rival the longstanding Billboard Hot 100 chart. Because Apple and Spotify both cater to different markets, it is worth investigating how fans’ tastes differ across those platforms.

Casually flipping through the past few years’ chart rankings, you’ll immediately notice that the majority slots go to male acts. That seems counter to the recent buzz. So what’s up?

• How big is the gender divide for top performers?
• How different are streaming charts from the more universal Billboard chart?
• Have audience’s listening preferences changed over time?

We can find our answers by looking to the stars! Well, if by “stars” you mean top performers on the charts.

First, a few considerations:

1. Because lots of individuals can be credited on a song (multiple artists, or multiple members in a band) we’ll count just the primary song credit and for bands we’ll look at just the lead singer.
2. Spotify chart means Top 200 chart. Spotify tracks the top 200 tracks but for consistency we’ll just look at the top 100. For this analysis, we took the data since July 2017.
3. Apple Music chart refers to Apple Music Daily Top 100 chart. The Daily Top 100 chart was released in August of 2018. We started tracking it in September.

A Gender Divide of the Charts:

How many women make it onto the charts at all? To answer this question, we compiled a list of over 104,000 data points over the last two years across Billboard, Spotify, and Apple Music.

The gender disparity is striking. Just like all the parties I threw in high school, the boys drastically outnumber the girls. Except that unlike my high school parties, all the people represented in these graphs are cool.

Let’s see how these ratios have changed over time.

Well that is interesting! A number of things to note so far:

• Gender disparities are large across the board. On all three platforms, there is a significant gender divide. Each chart has been cruising close to the 80–20 split of men to women.
• Streaming is making Billboard rethink what it means to be Hot. Before June of 2018, the connection between the Spotify and Billboard charts was looser but from June on the two start to align a bit more. After Apple Music joins the party and we are moving into 2019, all three charts are starting to look very similar. Those patterns coincide with huge growth in streaming and sequential changes to the way that Billboard accounts for streaming.
• Female artists are growing their stream-share rapidly. Over the last 6-months, the weekly average of Spotify female performers on the charts has achieved roughly 110% growth. On Apple Music we can see a whopping 145% growth. That growth appears more significant and stable than the episodic gains that female acts had in the past. There are a lot of peaks and valleys across the charts for both genders, but based on the latest trends, my guess is that female performers will at least keep their new foothold even if their growth slows. It’s also possible they keep climbing.

Digging Deeper with Chartmetric Scores (CMS)

Comparing raw counts of performers is a good start. However, if an artist shifts from No. 99 to No. 1, they still count the same. If an artist moves from No. 100 to No. 101 they no longer count. Moreover, not all chart-positions are created equal. It is harder to jump from No. 3 to No. 2, than it is to shift from No. 100 to No. 99. To see just how competitive the upper ranks are, look at a sample of song streams from a global chart:

Notice how historically a No. 2 track will have many more streams than a No. 10 track which in turn will have more streams than a No. 50 track. Yet tracks around No. 70 — 100 will tend to have pretty similar stream counts.

To account for the exponentially higher success reflected by the higher ranks, we identified a formula that estimates a song’s overall traction (the red-line). Using that formula, we calculate a single score that allows users to easily compare the overall traction of an artist or a song. We call that measure the “Chartmetric Score” (CMS). (If you’d like a more in-depth discussion of CMS, you can read more here.)

Chartmetric Score? Why is that interesting?

It is interesting because CMS allows you to track artists’ relative performance on the charts rather than just their inclusion on the chart. It’s like how FICO scores try to help you make sense of risk by plotting it in a single number on a linear line. Then, it is much easier to conceptualize what is happening.

At its simplest, higher CMS means an artist is doing great and lower CMS means an artist is doing less well.

With CMS, we can track how successful the average male and female artist have been, across our streaming platforms:

Spotify Top 100 Global

There are huge jumps on this graph for women (dotted line).

When a female mega-star drops an album (like Taylor Swift or Ariana Grande) you can see women leap ahead. But when the spotlight isn’t on a star, women’s relative success drops really far.

The good news for female artists is that women have frequent bouts of out-performing men. Moreover, in the past year or so Spotify’s CMS-values show a small but steady upward trend for female performers’ success and thus market share.

Apple Music Daily Top 100 Global

This is fascinating. That first half of the graph matches the patterns we’ve seen previously. Women move above and below, relative to men. Yet men’s averages hold fairly steady because they hold so much of the chart real estate.

But around February 2019, things change. Some of that major jump for women is due to Ariana Grande’s Thank U, Next release. More than that though, Ariana Grande was at the spearhead of a hail of great female-led tracks. The entire top 10 pretty much went to Ariana Grande (Brava!), but other female artists burst through the door with her and landed all over the charts (like Halsey, Billie Eilish, Cardi B, Lady Gaga, City Girls, Ava Max, and Ella Mai). Women holding so many top chart positions then drastically impacts the average for men.

That’s something new and different.

Moreover, around February, you can observe that the Apple charts were much more evenly distributed by male and female artists across the entire chart. It wasn’t just one or two female rockstars amid a sea of dudes.

That degree of equality on the charts is rarely seen.

What We Learned From Spotify and Apple Music Charts

• When women succeed, they succeed big. Across both platforms, when women enter the top 100 they tend to surge to the top of the charts. Either it is harder for female acts to linger further down the list, or perhaps there are just more male acts that linger in the top 100 but don’t reach the peak of the pile. Perhaps our next analysis should be on the lifespan of songs by male/female artists. Either way, when female artists hit they hit home-runs.
• Success is more concentrated for female performers. Male artists tend to have more conservative and stable reach, but women are less likely to make it into the charts overall. The averages for men are drawn down partly because male-led tracks routinely populate the lower portions of charts. For every male-led track with runaway success in the top-10, there is often a handful of male-acts trailing along in the lower ranks also.
• Hot and cold. It is not uncommon for women to have phases where they outperform men in regards to streaming reach and, thus, profitability. Neither gender has been simply winning out-right.
• Status quo no more. The old patterns don’t look like they are going to keep holding. Female performers’ success on Spotify has been trending up for the past year. On Apple, women just recently upset the gender balance all together.

Comparing Across Countries and Genres

If we want to get an idea for how influential gender is across music markets and genres, we can turn to Apple Music’s genre chart. We have been tracking this chart since Sep. 15th, 2017.

Again, a few considerations…

• We have data on more than 100 countries, but we will only look at the top five music markets: United States, Japan, Germany, Britain, and France
• There are 19 genres available, but that’s a lot to take in at once, so we picked 5 of the largest and most polarizing: All Genres, Pop, Hip-Hop/Rap, Country Music, and Latino.

I could play with this data forever. With just 5 countries and 5 genres, the following graphs contain info on over 900,000 chart positions.

First, let’s take a look at gender ratios across top music markets:

You can instantly notice that women hit the charts more often outside the US market — compare 24.9%(U.K.) with 14.2%(U.S.). By the way, Japanese listeners are really digging female artists — 素晴らしい (translate)!

Now, let’s look at this gender comparison genre by genre, beginning with Pop.

With power performers like Ariana Grande, Rihanna, Camila Cabello, and BLACKPINK we could have expected the ratios would be more balanced here. Women are clearly the Queens of Pop. It is the genre where they shine the most.

American Country music is received very differently in its domestic market compared to foreign ones. Women are killing it on the Country music charts outside the US. Johnny Cash still tends to have the most tracks on the French and German charts, but otherwise its mostly ladies leading the pack: Shania Twain, the Dixie Chicks, Taylor Swift, and Dolly Parton are adored. Newer male country acts like Eric Church and Zac Brown Band struggle to land.

Perusing the Japanese “country music” charts is almost synonymous with just looking at Taylor Swift’s discography.

Hip-Hop/Rap is the hardest genre for women to make headway in. American and French listeners seem very resistant to embracing female artists. Other markets are more responsive… just, not that responsive. For the past few weeks, Cardi B and City Girls have been doing the heavy lifting for defending women’s foothold in these genres.

Recently, these charts have been filled with numerous tracks from Bad Bunny, Ozuna, and Anuel Aa. It’s hard for any other artist, male or female, to break the hold those megastars have on the Latin charts. Also interestingly, many songs in this genre are collaborations and feature prominent women artists (Cardi B, Selena Gomez, Demi Lovato), but the first billing still tends to go to male artists.

Final Thoughts

How do you think these trends will change going forward?

Perhaps the growth of streaming, and women’s tendency to drop mind-blowing tracks has started opening new doors. Will women continue to get more of the coveted chart positions? Or after the recent reign of Ariana Grande and Billie Eilish, are we due to see fans pendulum-swing back to more male artists?

Apple Music and Spotify trends give us some insights, but of course music streaming is a wide world with many unique platforms. Still, the big changes taking place suggest that streaming-growth is disrupting old listener patterns. You should keep your eye on how audiences are engaging with top performers because “the times, they are a changin’.”
