iTunesdl, iSuck, et al.
Has anyone used any of the tools out now that allow you to download people's shared iTunes music? I've given them a try, and, well, it's great. But I have a feeling they're going to be shut down by Apple. You still can't play other people's protected (iTunes Music Store) AAC files, at least until the DRM is cracked, but I don't think they want the publicity of iTunes being a P2P app.
