multiple bgms on loop plus shuffled

I want to make an area where there are (lets say 5) bgms playing one after the other randomly - is this possible? and if so how would I do that

The easier way is using a Parallel Processing event (a map one or a event one). Just starts a timer with the music duration and when this timer ended, start another music with another timer. I am unsure about battles and others things that may mess with the timer. Untested.
