Classic sounds?
 

I tried moving the 4-5 mp3 files (combat1,2,eqtheme,death theme, and maybe something else) to my back up folder. but now, no music is playing. sound effects works perfectly fine and yes I've checked to make sure that music volume/combat music/environmental sounds were all turned on.

before I moved those files into the backup folder they did work but I prefer the originial midi sounds
