I don't mind the BGM of the game, although to be honest I usually play with either my own music on and voices on or everything off.
I will admit I leave the background music on if I'm too lazy to put a record on and feel like listening to something classical, but 90% of the time the only thing I hear from my FKG game is either Dogwood's silly broken Engrish or the music right before I mute the game as I log in.
