it's a person 2 person mp3 transfer program, very much like kazaa but honestly it's completely pop-up and add free. It's simple to use and I've never not found the track I want. It will also bring up the track if its now available for immediate download as too many people are downloading it so that you know it's available and you can download it when it's next free it you leave it running.

I've got about 300 mp3's of all quality and hard to get hard trance / hard style in about a month of average use... of course I've got broadband!

Very very fast to.
