Addition of Disc lore of Disc 5, 11, and 13

With the next update which is the "Bundles of Bravery" I think minecraft should add a Music Disc that goes along with story/lore of the Discs 5, 11, and 13. But just like disc 5 which can be found in the ancient city, it has warden and ancient city appearances through it's noises that you would hear if you yourself where in the mysterious city underground. With this disc let's say for example Disc 7, it should have appearances of the creaking and pale garden through their noises but corresponds to the story of the discs 5, 11, and 13. It would have players creating new theories, ideas, thoughts, etc. And have people curious of what is happening in the story. From 2 of the discs being dropped by creepers, one Disc being found in the ancient city, and finally would have a Disc from the pale garden.
