Well I just asumed music was being streamed from disc in pygame.music:

import pygame
pygame.init()
pygame.music.load('some_file.ogg')
pygame.music.play()

I have never used pygame.music with .ogg files larger than 5 mb, so I
cannot say whether my assumption is valid or not.

What file format are you using?
