I have it so at first it plays title screen music and when you click on a sprite is stops the audio from the title screen and goes to whatever layout I want. I have it so on that layout, I have on start layout to play world 1 music. It doesn't play the music when I preview it starting with the title screen layout. If I start the preview on world 1 layout, the world 1 music will play. This could be a bug but I don't know.
