It depends on the ship really. My squid requires afro-funk or new wave grooves, my junker needs some rough sounding bluegrass to carry me through the skies, if I am flying a galley I am shouting at the AI with my mic because they won't man the right guns or repair the right shit so no time for music.
(I just assume all Goldfish captains are listening to Ace of Bass or something like that, makes them feel real pretty.)
