Minecraft wiki entry for Music, associated text: If none of the previous criteria are met, but the player is in the Nether, a random general Nether track or a Nether biome-specific track plays, except warped forests, which don't have any music. If the player is not in the Nether and is currently in Creative mode, a random track plays (Creative only on Bedrock). If the player is not in Creative but is currently playing (i.e., not on the menu screen), a random general track plays. These tracks all play 10 to 20 minutes after any currently playing tracks are finished.
