Random Ramblings

I can't believe how late I am to this party, but I am now addicted to soundtracks that go with my fave stories. I guess it started when I began downloading fics to my Kindle, and then could read anywhere often while listening to my Ipod. So... a request: What are the best story soundtracks? Or which ones do you love and recommend? I have found several, I am currently in love with the music for Apocalypse Z. I love humor, and also when the music really adds to the story. So any suggestions?
