I'm big on playlists, so I usually can either listen to a rock playlist or a playlist of my favorite songs (which is stuff from all genres) and either can maybe help change my mood.

I say rock because it is aggressive, so it'll move me farther from being "down" or depressed and a little more towards aggressive, pumped up or some similar feeling. By the same token, you'd think stuff like rap or dance music would do the same, but it doesn't, really--maybe because I like rock and its subgenres more overall. I do have a lot of mainstream pop on my favorites lists (there are multiple ones), though, and some are uptempo songs...but I would not say it's in that dance music genre, which I think of more as club, electronica, house, techno, etc.
