Natural Music Discs through commands/creative

These music discs would be for all the songs in game aside from the ones originated from discs already, and would only be obtained through commands (maybe creative inventory as well, if you want).

Those include ALL ambient songs in Overworld, like Minecraft, Sweden, Living Mice and Key; The ones at the Nether, such as Concrete Halls and Warmth; The ones by Lena Raine for 1.16, like Chrysopoeia and Rubedo; The ones that playing during creative mode, such as Haunt Muskie and Aria Math; The End song and Alpha. Every song in the game that is not a disc would be included.

I believe the reason they didn't release the songs in discs was because they didn't want to give the players the ability to easily change the atmosphere, but if they added as only obtainable through commands they make sure players won't stumble across them accidentaly. They could be really useful for custom maps, and would sync well with my other idea of Gamerule doNaturalMusic to disable naturally playing songs
