Ever want your own theme music?

I've always thought having a perpetual theme music would be awesome. But not the same song all the time; if I'm pissed, the music is pissed, or if I'm determined, then the music is badass. Some songs are perfect for it.

Well, I've found my main "awesome" theme song: Seven Nation Army (Electro-remix), minus the lyrics, of course. This would be the song that plays when I get out of my car, open a door, or some other type of entrance.
