This one classifies as a mini-killer-app. Sonific is a nifty new site that almost instantly creates free customizable music players that stream a song from almost any web-page, blog, social network profile, or photo-sharing site. Currently, SongSpot in beta and only available by invitation, but when the service goes wider the possibilities for easily adding music to any web site seem endless.
Check out the SongSpot for Jim Weider the former lead guitarist for The Band.
