The Recording Industry Association of America (RIAA) appears to have ankled popular (but illegal) music-sharing site Muxtape.

"Muxtape will be unavailable for a brief period while we sort out a problem with the RIAA," the site's homepage says.

"No artists or labels have complained. The site is not closed indefinitely. Stay tuned," the company says on its blog.

NYC-based Muxtape, founded by former IAC/Vimeo staffer Justin Oullette, launched this past spring, and is funded by his former boss -- Vimeo cofounder Jakob Lodwick.

A similar (but legal) service called 8tracks recently launched.
