Fawkes,I think (though very possibly wrong) it's a bug with `pygame.mixer.music.play(-1)`
You can use numpy / pygame.soundarray to to create smooth loops though I can't recall exactly how.
Marcus may be able to assist you with that
- The song is in .ogg format and plays fine in both VLC and iTunes - When playing the song for the first time in a pygame program it plays fine - When the music begins again when looping, there is a significant audible static.
