Background music plays when the music setting is "OFF"

While playing the background music still triggers despite the "Music: OFF" setting in the options.

Turning the music volume up then back down to "off" fixes the issue.

The music does not appear to play for the rest of the session if the above "fix" is applied. But when the game starts with the "music off" setting, the music can play.
