Blergh bb code messed up and there is no editing here.
Let me clear that up:
Or just name all of the music
CHANGING bricks something like 'Music1' and then make these events:
>[] OnActivate > [Music output brick] > setMusic [some song]
>[]OnActivate > [Music1] > setRaycasting [ ]
>[30000] OnActivate > [Music1] > setRaycasting [X]
