Napster is essentially using the music to make money for themselves and that's the part that's both morally and legally wrong. That I think is more relevant than whether or not I'm losing money. ↗
With Napster and the sharing of music, of course, there are going to be people who exploit it. Greed has no end. But there's a lot of good that could happen. We shouldn't let the economic concerns of the major labels infringe on our freedom to share music. ↗
