Just to be clear, you need to play two different multi-minute sounds at
once?
Because your example has one 13-minute track and one 3-second track. If
those are the sounds you need to play at the same time, why don't you just
preload the 3-second one into a pygame.mixer.Sound object and play it
whenever you need it, and play the 13-minute one with pygame.mixer.music?
