Mojo, as far as downloading music goes I can help you out there (having just short of 4000 songs on my computer). I used bitcomet as a download client, and search through the torrent sites to download music. Torrent sites are only good if you want to download an entire album or what I do with many artists is download an entire discography! You can't download single songs on torrent sites. For that I would recommend limewire.
It takes a little bit to get used to bitcomet, but I'd be more than willing to help you. Just let me know.
