I'm not angry very often.

Day 20: A song that you listen to when you're angry.

This is a tough one because I'm not angry very often. 

If I'm mad enough about something to blast some music and try to dwell in the emotions, I usually pick a somewhat morose song that won't overly depress me, like "Boston" by Augustana.

But honestly, when I'm angry, I don't usually listen to music.  I usually write.
