It's a lot harder now a days Mike....lots and lots of virus's in file sharing now.
I use a few but music is a low priority to me.
I use bit tornado for torrents.
You must register on this one.
http://www.filelist.org/ My favourite but not many files...great for games..no virus's and if their is they get delited immediately.
They also have a MP3 site and another site that I will not mention on this forum...you will see it.
Another good one that you dont even have to register is
http://www.torrentspy.com/
I use about 5 sites but their is heaps.....
I would never use sites or programs like Kazaa where you are downloading directly from pier to pier...to high risk for spyware and virus's
