Sometimes, when I'm at the PC and listen to music, I just have to get up and start dancing around like crazy lol Headbanging included :P
It can be all kinds of music, but it has to have a good beat to dance to and it also shouldn't be too slow.
Today it was Misfit Love by Queens of the stone age.
I remember I was really mad once and just jumped around the whole time listening to Linkin Park (Numb and Faint probably).
Dancing can be a great way to cope with anger, or just having fun.
