Here's a great summary of why the current middlemen between musicians and listeners are deservedly doomed: "How I Became a Music Pirate".
As dubious as it is to denigrate music sharers as "pirates", it's just as goofy to adopt it as a term of pride (ironic or otherwise). Technology, ethics, law, and business models are crazy unaligned right now, but "pirate", even as a denial, allows the moribund middlemen the rhetorical floor. There's nothing wrong with trying before you buy or sharing with friends. Like it? Be honest and buy the t-shirt, go to the show, subscribe to eMusic and (re-)download it, give the musician free advertising on your blog. But whatever you do, kill the pimps!
Currently listening to: "Tabula Rasa: Silentium" and "Collage über Bach: Toccata" by Arvo Pärt. The "Sarabande" is heavy as hell!@$#
