Not that I'd use it, but my imaginary friend likes to use torrent sites like isohunt.com, or activedots.com along with a program called utorrent
to download different material. The problem with Limewire, Frostwire, Bearshare, etc. is they are extensive programs that can hog memory from your computer and really slow it down. The only down side to this other way of doing things is you will usually only find full albums instead of individual songs.
