As a musician who is in a local band, I encourage people to rip my CD and put it out on torrent sites, and if we get signed to a major label, I'll still feel the same way. I think the RIAA is and the whole concept of charging for mp3s (drm etc) is pure BS.
If I like a band enough, I buy their album, one because I like to support bands I like, and two because the CD is a collector item, along with the insert etc. If I want to see what a band is like, I see nothing wrong with downloading their album -for free- and giving it a listen for a few weeks to see if it grows on me or not. If it doesn't chances are I'm not going to listen to it enough to justify the price of buying the CD physicially or digitally, if it does, then I'm probably going to go and purchase the CD to support the band. Simple as that. Personally I think its a great way to give alot of unheard of bands some great and well deserved exposure. I can't tell you how many new bands I've found because of giant genre lists people seed. And out of those new bands, I've purchased many of their CD's.
People really need to stop whining just because it has been deemed "illegal".
Heres an excerpt from Wikipedia quoting Disturbed's frontman David Draiman. I couldn't agree more with him:
