This is a project I made for my LEGO Disneyland. Just hit the green flag and it will play Main Street music. Then hit a button to play some music, when you want to stop it hit the button again or hit the green flag again.
UPDATE LOG v0.3 - Added a Next Song button and a Main Street button to make it easier. v0.2 - Added Cantina Inside, Empire and Battle for Star Wars World. v0.1 - Added Christmas Main Street and normal Main Street music, also 30th anniversary parade music for the release.
