Creative Music

Minecraft has 6 unique music tracks which only play while you're in Creative mode.

With this resource pack, they also have a chance to play in Survival (alongside all the regular tracks). Also, all Survival mode tracks will play in Creative mode.

Note: This doesn't add any actual sound files to the game, it just reconfigures the way music is played. It should (hopefully) be compatible with other resource packs which add their own music.
