(If you're on a console, you can listen to your iPod, I guess. In that case, limit your list to 20.)

I've considered using the http://www.fallout3nexus.com/downloads/file.php?id=1418 mod, but haven't sat down and did the necessary conversions to make the music work in game.
100 songs is a bunch.
What do you listen to when you listen to music while playing?
