I don't make B.S. rationalizations about it either. Copyrighted music is not mine to take, or to share. I pay for the things I own, thank you. The main reason Napster is so popular is because youth in this country are not taught by adults what private property means , or that music is a kind of property. In high school, I used to make copies of other people's music onto tape.
Adults have no excuse.
And everybody knows it. If you want to be some kind of Marxist idiot, feel free. But don't force other musicians to give up their work. Let them make that decision. Then post a comment.
