something just jumps out and shouts "TRAP!"
I just can't imagine that google would go against the RIAA with something like this unless there was a reason for it. After all, I would have to say that probably over 95% of the music uploaded there is copyright protected.
I don't think the RIAA will let it go for too long before they jump on it, and the way the copyright laws have been rewritten in the past few years, Google and the ISP's won't have a choice except to give the RIAA what it wants. Identities...
