I have been using MyKazaaGold for years and have never had a problem. You get to download unlimited music from just about any artist under the sun and you never have to pay any fee's per song. They also don't bundle any spyware or other garbage with their software, so it's really safe. Check it out: http://www.MyKazaaGold.com
