So your target market is the new gen millennials? I really don't have a specific music in mind but for those market, maybe an upbeat background music would be good. Upbeat but not deafeningly annoying.

That would hype their mood but keep them focused. I personally feel that way whenever I hear an upbeat music and I guess it also pumps the adrenaline. Original music would be good as well so there would be no copyright issues.
