Turning down the jukebox music in Diva room?

So I set myself up a playlist for the Diva room, but for some reason the music plays much louder than what I have the game volume on. I play my game with surround sound, and both the jukebox music and the game music play that way, but the jukebox music just seems to over power the game sounds/music.

When I turn down the volume on my speakers, the game volume obviously goes down with it, so I can't really turn it down that way since I can't play the game songs with no volume. Is there a way to turn down the jukebox music in game to better balance the sound?

I've tried messing with the BGM setting in the game menu, and while it did turn down the jukebox music, it also turned down the game music, so it pretty much has the same effect as just turning down the speakers.

I've also tried messing with the PS3 music volume without the game on (pressing triangle while a song is playing and going to "volume control" or w/e) but after turning it down and going back to the game, it's back up to loud volume, so it must feed off whatever the game volume settings are, and not the PS3 itself. It's rough trying to listen to songs at the volume I want the game music to be at ><;

Any ideas? O_o

Thanks in advance!
