^just a note, they are by the same company and they are the same program. using torrents like that has a high risk of screwing up your computer and promotes illegal pirating of musicians work.
I don't even use those p2p programs anymore, I got most of my songs from another source (not torrents) and then I got all my other stuff from torrents. The last p2p program I used was Aries a long long time ago.
