Yes. Bittorrent, in all of it's different flavours, can get you plenty of spoof-free, high-quality audio. Entire albums can be found on websites like
Suprnova.org, and you can easily search that website for whatever you need. Some personal favorites of mine for Bittorrent include a java version of Bittorrent called
Azureus, and another if you don't have java is
Nova Torrent. It's a bit more bloated than Azureus, but nowhere near as bad as BT++ or the original BT. I hardly ever use kazaa anymore, it's far too filled with spoofs, looped songs, and malware for it to be worthwhile. Kazaa, for me, is an absolute last resort.
