Muxtape RIP? Noooooooooooooooooooo

Another post by Geoffrey Ellis:

Looks like the RIAA has shut down the user generated audio streaming mixtape site Muxtape.com for the time being. A note on the front page of the site says:

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

And the August 18th Muxtape blogpost says: "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."

I can't find much other info on the muxtape situation other than my assumption that the RIAA can't find a way to play nicely with the new realities of music dissemination. I imagine it has to do with the fees
associated with streaming audio (the streaming cost of one song currently runs $0.0008). Anyone else have any info? Sad to see it go. Hopefully it will be back in it's same awesome state and not some sucky watered-down version.
