// Menu music spans Intro -> MainMenu -> LevelSelect as one continuous track
// (Phaser's sound manager lives on the game, not the scene, so a Sound
// object started in one scene keeps playing through scene.start() calls
// into the next). playMenuMusic is safe to call from every one of those
// scenes' create() - it no-ops if the track is already playing so
// navigating between them doesn't restart it.
