Dynasty Warriors Gundam Reborn Custom Music

For months now I've tried to find some kind of discussion or inquiry into the functionality of custom music tracks for DWGR but seems like it's something thats never been brought up, it doesn't work. I can access the song list but when you click on one the emulator crashes and gives this log

So is this a specific game issue, emulator issue, or a settings issue? I'm pretty sure custom music works in some other games so not too sure if its an overall emulator issue. Obviously a fix would be just use a media player but this is a permanent track replacement feature so it takes advantage of tracks switching mid gameplay or for cutscenes so for compatibility's sake I'd say it's pretty important.
