Fade out music to current map

[Seedonator]

Aight so I have this script where when you open this menu it plays background music. Thats working fine, but I want it so that when you close the menu it fades out the music and then plays the music according to the current map you're in.
This is the part of my script here where it fades out the music:

choices = []
      choices.push(_INTL("Yes"))
      choices.push(_INTL("No"))
      command=Kernel.pbMessage("Are you sure you want the quit GTS?",choices,choices.length)
      if command == 0
        pbBGMFade(0.8)
        pbPlayCancelSE
        @exit = true

I put pbBGMFade(0.8) in the script so that it fades out the menu music, but it just fades it out into no music rather than the music of the current map you're in. How do I make it so that it changes the music to the map you're in?

Edit: nvm all I had to do was add $game_map.autoplay in the script and now it works.
