As the article itself states “I won’t waste your time getting into the ethics of file-sharing, or the debate over whether it helps or hurts record sales”. (Although I think I agree with most of Meg’s comments on this topic).
I have to post this: How To Survive Without Audiogalaxy: A Guide to File-Sharing Alternatives. I’d already tagged onto a few alternatives a while ago, and to be honest I’m only really posting this so I don’t lose the link (it’s currently at number 2 at DayPop but better safe than sorry).
