people who use music in their games:

Do you prefer more atmospheric music (i.e. video game music that is instrumental) or like to use songs with lyrics?
Or do you go straight to pop songs (or metal, or 80s, or whatever your genre of choice is) on full blast?

@Miru - Depends on the campaign, really, but instrumental seems to be the best for most sessions. My group has a habit of having intro songs for each session that usually have lyrics, too.
