Try the BitTorrent sites, they are the new wave of downloading and it is nothing like Kazaa or Napster. (oh wow, didn't realize you mentioned it JBFF)
What you do after you download the software you look for the media on websites in a search engine that are torrent sites. I missed half of Enterprise:Storm Front II so I went on GOOGLE typed in ENTERPRISE STORM FRONT 2 TORRENT. And came up with this site.
Or you can try this Russian website which the songs are like 2 cents each and they have full licencsed rights to them. You pay through paypal.
