Atheist/freethinker music

I came across two pieces of music which "sturck a chord" in me. 

First one is "I Ain't Afraid" by Holly Near.
The other one is "God Thinks" by Voltaire. 

I'm not quite sure about the legality of the last link, but Voltaire has the song on his website (link of which I displaced) so I hope it is OK. Both found through Humanist Network News Podcast.
