I use
www.Bearshare.com for P2P and its excellent. I just saw that BitTorrent thing on the BBC website, and I'm going to give it a try tonight. I used to have moral objections to downloading music from P2P but after buying the new foo fighters cd this week only to find that I cant copy it to my MP3 playerdue to copy protection put on it by bertelsmann, I will now download with impunity.
