Repeats: Try for no more than 2x/day on any given song, no closer than a couple of hours. 3x/day, pushing it (and keep the distance between).

"Traditional" songs for breaks (Macarena, YMCA, Cha-Cha Slide, Cotton-Eye Joe (which I happen to like), and that sort of thing): Keep them for field outages or elimination-round breaks. Maybe you don't get to all of them. That's probably a good thing. But don't go playing them during the normal matches unless there's some form of field failure.

Thought input: Also see "What you want to hear", but if you're doing the music, think about the audience and what they'd want to hear. Don't just put an iPod on shuffle; one of the better-DJ'd events I was at (OK, VRC events--but at the time it was FVC) had "Eye of the Tiger" and the Imperial Death Star March (or whatever it's actually called) in the playlist (though the playlist should have been longer...). Think about what the audience is going to like, what the energy level needed will be, sprinkle in some surprises.

What you want to hear: If it's an FRC event or something like that, try to keep it clean and family-friendly. Remember, your younger siblings, or someone their age, are probably in the audience (especially true for the high schoolers), and maybe they don't like listening to the same music you do.
