There's an important aspect to using music as a mood changer: It will only work if you start out with the music that *matches* your current mood (and sometimes that's enough, hence the Megadeath and Dubstep stuff people talk about to calm them down). 
If you're in complete bounce mood, chill out music usually doesn't help much. You need the music to catch a hold of your current mood and then gradually take it to the desired mood. Same if you want music to cheer you up: Listening to happy stuff when you're really sad or down is pointless. Start with some depressing music and then work your way up to lighter stuff. Your mind will follow.
