Can you name some classic or soon-to-be classic protest songs? (Details)

The Jellies have been great about answering my requests for music/songs before. I’ve gotten some great suggestions.

Now, I’m on the look for some good “protest songs”. They can be of the “we shall overcome” variety or a “peace” song (like “Imagine”) or quirky-powerful like the songs of Malvina Reynolds.

If you know of a good protest songs/CD/albums or even artists who specialize in these…please let me know. Throw in your favorites!

Thank you!
