pygame Sound

pygame.mixer.music - intended for background music

music functions are similar to Sound functions, except that they don't load all the data into memory at once

This makes a difference for very large sound files, such as background music

pygame.mixer supports exactly 1 music track at a time

  pygame.mixer.music.load('musicfile.mp3')
  pygame.mixer.music.play()
  pygame.mixer.music.stop()
  pygame.mixer.music.fadeout(1000)
