When I was a teenager, my dad used to give me shit for saying that “happy” music (by which he meant lilting classical or, like, 1950s pop) made me mad, while “angry” music (metal, rock, dance) made me happy. Basically because I didn’t (and still, for the most part, don’t) enjoy the former, while I do enjoy the latter.

Well you know what, dad? According to Science I was right; listening to metal can decrease anger and increase positive emotions. So hah! Science!
