How to have inserted music play in FEXP?

Alright I know how to import the music I want in the game, but I could not find any tutorials on how to actually place the music into the game.

I would think for boss music it would have to be an actor event but I don’t know how to do that.

As far as the map music went, I opened map properties selected auto change bgm music and selected my song, but when I tested it, it would play for like a fraction of a second and start playing the Distant Travels song again.

Help pls.
