Many of the composers I know do not care if their music is distributed. They see it as a genuine showing of interest, which shows that they have succeeded in writing music that appeals to people in whatever way. If I were a composer, I think I would feel the same way. When I download something by a given composer or performer, I still feel the need to go out and buy a CD of theirs. I don't see downloading as a replacement for buying, but rather as an incentive.
