Minecraft wiki entry for Music, associated text: Music tracks can play at various points during gameplay. Some types of music are triggered by events, while others play randomly while certain criteria are met. The song "Alpha" always plays instantly during the credits, and the song "Boss" always plays instantly while the player is in the End if the ender dragon is undefeated or resummoned. Both of these tracks start playing in place of any already playing music. If the player is in the End and the ender dragon has been defeated, the normal End track plays 5 to 20 minutes after any currently playing tracks are finished.
