In a recent online interview, Barney was asked what he thought of Napster. He said something to the effect of: he didn't like it, because "he couldn't feed his family" if everyone used it.
But isn't it true that people buy in the store the music they really listen to? I like Joy Division, and I legitimately own everything they've put out (the albums, the box set, the BBC CD, ...). If a CD were released with all the rarities that have yet to be issued, I'd buy that too - even though I already have the music.
I've found in general that if I'm interested in a band, I check them out with mp3's. And if I like them, I buy the CD. If I don't like them, sooner or later I delete the mp3's. Isn't this the way most people are? I don't like mp3s by themselves - I like owning professionally created CDs. Any takers?
