What are good songs to make a soundtrack to A Clockwork Orange?

I'm doing a school project. I just read A Clockwork Orange and one of the project options is to make a soundtrack with 3 to 5 songs on it and a written explanation as to why. I already have Beethoven's 9th Symphony and Rob Zombie's Never Gonna Stop(The Red Red Kroovy) but I need at least one more song! Any ideas?
