I use Vuse (Azureus) on Mac OSX. There is also a uTorrent beta for Mac but I haven't tried it.

For downloading albums, check some tips here: 1. http://www.gnutellaforums.com/open-d...lbw-files.html and general tips for downloading music here: 2. How to find music.

For mac of course you would stay away from WMA or Real Player files, which in any case are patent formats.

One way to find torrent sites is to google search for the name of the artist & album & put the word torrent after it.
