Coming from a guy that has close to 10,000 songs, use
torrents for full albums and Ares for P2P and just like one or two songs. Ares is by far the best P2P I've used and the only one besides WAREZ I trust. But do as Freak suggested earlier, use a simple BitTorrent program and download from torrents. I reccomend either Azureus, uTorrent, or my personal favorite, BitComet. I suggest BitComet just because it has an easy user interface and a simple design. No problems here. Just make sure you update frequently, so you get the best download speed.
