Muxtape Shut Down By RIAA

The front page of the popular online mix tape service Muxtape began carrying only this message yesterday:

Muxtape will be unavailable for a
brief period while we sort out a
problem with the RIAA.

No details are being provided as to the nature of the disagreement, though a Muxtape Tumblr blog post shared:

No artists or labels have complained. The site is not closed indefinitely. Stay tuned.

Beta users of Muxtape For Bands: you are unaffected by this outage.

More details as they become available.
