The Skittles-colored Web 2.0 chaos that normally greets you at Muxtape.com has been replaced by the notice “Muxtape will be unavailable for a brief period while we sort out a problem with the RIAA.” Given the RIAA’s attitude toward people who do anything with their music besides listen to it alone in a locked room with the curtains drawn, it’s no surprise they have a problem with Muxtape–I’m surprised it took them this long to make trouble, actually. And given the RIAA’s preferred means of “sorting things out,” it’s hard to be optimistic about Muxtape’s future.
