So does that iPhone Torrent track your progress on your desktop, then? That's awesome. If there's a way to bundle that and pass it along, I'd love a chance to try it.
I use Transmission. And while I can't say I've never downloaded music, I will say I'm very picky nowadays about what I grab. I can justify downloading an album to give it a try, and then if I like it I go buy it and if I don't I delete it. Not really that different from using (free) Rhapsody to sample whole albums prior to purchase / not purchase, ya know?
