jukebox plays over top of audio from default music

Music from the jukebox now plays over top of the audio of the default game music. You can hear both if you are playing a song with the jukebox and the default music is also playing.
I noticed this after I had started a song on the jukebox and then heard the default music in the background while the jukebox was playing. I then stopped the jukebox and could clearly hear the default music playing.
