SetWindowIcon(0,3) does not work in the above code. SetWindowIcon(0,3) can work if I put LoadMusic("Various/011.ogg") in another location mentioned in the above code. 

Furthermore, if I don't use ogg file and use a mid file, the above code can work without problem no matter where I put LoadMusic("Various/011.ogg").
