I'm aware people can still have the rights to own their self-released things

Not to my knowledge. They do have their own label for everything other than The Money Store (which was released on Epic), so it's possible but very unlikely they would give permission.

- ensure that the Name (which includes any confusingly similar name) is not the first word, doesn't use any - other aspect of any of our Brands or Assets as part of any related branding, including as or as part of any logo;
- make it clear that the product is unofficial and not from Minecraft or approved by Minecraft.

tl;dr
- credit the music author, not Minecraft
- can't promote the game as "having music from Minecraft" or implying partnership or official ties with Minecraft
- can't use their content as promotion for the game itself

Follow those, and you can technically use Minecraft's music in-game, since Minecraft is ok with its use in non-commercial ventures under these guidelines. Can read more about it here. https://account.mojang.com/documents/brand_guidelines
