Be careful if you do it, it all depends on your school. Mine will slap a $50 fine on you the first time you get caught, then $100, then you lose your internet privilege for the rest of your time at the school. I've downloaded via torrent twice this year, three times last year and I've never been caught.
Also, a lot of schools only crack down on torrents and p2p programs. If you're only really looking for music, there are file sharing websites that will let you download for free.
