[>BKA< T Wrecks]

Well, a band like Bon Jovi (just as an example) sure earns loads of $$$ on a tour - but smaller bands often earn nothing more than the net revenue from their own merchandise sales (T-Shirts, Patches, CDs and stuff).
A free music platform would indeed be nice - especially since many smaller bands offer much stuff on MP3 anyway. However, it's difficult to dig through scores of band homepages to grab that stuff. A centralised platform with short genre info (or better, description), maybe even from the band itself, would be nice. And a rating system, why not. I mean, if I was a big fan of stoner rock and I saw some songs by a an unknown, but top-rated band that describes itself as a mixture of, say, QOTSA and Spiritual Beggars, I guess I'd go ahead and d/l that shit. And if they had a comment in their MP3 tag saying that you can get their entire album as a nicely packaged CD with some material not available on the net, complete lyrics and everything for a reasonable price (like 10-12 $) directly from the band, why not?
But the music industry... nah. They'll never get it - and IMHO, they don't deserve any better if they can't come up with better stuff than what they're offering right now.
