Muxtape – the popular online mixtape service that allows users to make 12-song playlists of their music and share them online – has been temporarily shut down to resolve an undisclosed dispute with the Recording Industry Association of America (RIAA).

There’s no specific reason for the shutdown listed on their site, though it is likely due to it’s recent rise in popularity, including a slot on PC Magazine’s Top 100 Undiscovered Sites.

“No artists or labels have complained,” Muxtape wrote on its Tumblr blog. “The site is not closed indefinitely. Stay tuned. Beta users of Muxtape ForBands: you are unaffected by this outage.”

When is the record industry going to wake up, accept reality and join us in the 21st century?  Not soon enough apparently.
