It depends on what you're playing. ("Gaming" is such a broad, vague verb.)
When I used to play RTSs, I listened to some power metal, and when I played something like racing or fighting games I listened to pop and rock, or anything else that sounds fun.
Other than that, I don't really listen to music while playing games. The soundtrack is usually enough, and listening to any music I already know is distracting, whether there's lyrics or not.
Why do you have trouble concentrating on the game?
