Well
You could put the bricks (I presume you are using more than one music brick) on a flat basplate (it's not spam :D). Then go to Events>OnPlayerTouch>StartEvent(or something like that)>named brick>Music1
Repeat this with the next few plates, changing the Music brick's name.
Also, to end event, just place an invisible 1x6 or something across the ends of the plate(s) and put Events>OnPlayerTouch>CancelEvents(or something like that)>named brick>music1
Repeat for infinite silence
