Name a song or songs that brings you up when you're down, or calms you down when you're mad, or makes you mad, etc. etc.

I've found out when I'm down and need something to bring me up, or if I am mad and need something to calm me down, Coldplay's Yellow works for me!

As for something getting me all pumped up and angry.. probably.. anything hardcore.. especially Slipknot's End or End of Everything, whatever the name is.
