This is my opinion. I think it is ok if a band doesn't care. Groups like Radiohead, U2, Rage Against the Machine, and even those losers, Limp Bizkit (they got paid millions for supporting Napster so...), don't care if you distribute their songs. If I don't hear at least 3 songs that are good from a CD then I usually don't buy it, and I buy a lot of CDs, too. File sharing has actually increased the amount of music I buy, and I am hardly ever let down by the quality of the CDs I buy. I think one of the fears that the record industry and musicians have is that people will hear a few songs that are downloaded (besides the single on the radio) and realize that the CD sucks. The record industry would actually have to find good musicians and musicians would have to actually be able to play and write something meaningful to get a record deal. They could no longer rely on commercialism and their one good song to make their millions. That's just my theory.
Tell me what you think.
