I do honestly love the music Jake, it's very up beat and energetic.
Personally I think that each room should have a different tune, because otherwise the song gets a bit repetitive throughout the time your playing.
For example the castle can have a more sinister tune unlike the harbor which could be more upbeat.
It just gives more variety to the game, and I also in some other VWs I like to move around the rooms to listen to the music
