An awful lot of my choices have been mentioned here so I'm not going to list any songs, I'll just say that music keeps us from being the (adding) machines that our current culture encourages us to be.

I've heard Helen Schneyer sing "There is a Fountain Filled with Blood," and it was moving, and it was wonderful because Helen is a truly great singer. But it was still more moving, and somehow stronger and more militant at the same time, when Charlie Baum sang it late one night at the FSGW Getaway.
