background music only plays sometimes/glitches

[eos1001]

i recently downloaded a custom soundtrack with aphex twin,drumnbass ect and the music keeps glitching for example

whenever i get into a battle when the battles over the battle music doesnt stop playing so its like a nonstop battle 0o

when i first start the background music works well no matter where i go but sometimes the music doesnt play at all

like ill get in a battle and no battle music or when i go anywhere no music all i hear is the wind >.<

 

does the latest patch fix the music bug, cuz i havent updated yet
