Bout time a mac person is up in here. Try Limewire. It's one of the best mp3/file sharing applications out right now. Not only can you d-load mp3's but also, programs (don't get to happy, most of em' are PC based), video, images, and documents. It's very phat!! Just came out with a new version too!! D-load it at Limewire.com. Enjoy!!
