As the title says, what do you listen to while playing? Notice that playing doesn't imply that you only play elements, but other games work, too. Oh, "games' audio" is an acceptable option.
I, myself, use to listen to some songs looped. I pick one, loop it and then, after some time, change it to something else. Right now (and most of the times) it is
Omoide wa okkusenman!, by Jam Project, but sometime I switch to the original one, even though this one gives me more energy while playing (Okkusenman means "boundless", "limitless" or, litterally, 110 millions, and in the whole title it means "memories are limitless", or "infinite memories". If you don't know the song, search "Okkusenman" on Youtube and pick one with eng subs, you will be astounished from the meaning of the song, I assure you).
Other songs I use are "Airman ga taosenai", another energetic song, Ano hino boku e, litterally, to the me of that day, another awesome song in terms of lyrics, and some Italian songs, plus Linking Park or Red Hot Chili Peppers.
