Does music affect the way a person thinks or acts?

I've noticed abrupt changes in my attitude that could be ociated with the music I am most currently listening to, but it could also be who I am talking to or my surroundings. But when I am feeling inconfident or unsure about something, as soon as Porcelain and the Tramps come blasting in my ears I have a sudden rush of rashness that kind of makes me do stupid things. Just wondering...
