Custom music cutting off after playing for a few seconds

[ttttdoy]

I'm not entirely sure what's causing this but here's my modlist to see if anything looks out of the ordinary

Also the wiki entry for actually putting in the custom music should be updated to say that anything other than 16-bit pcm wav files will work, any other export method will just crash the game
