like yeah there are lots of other keys but functionally keys of the same type (like all major keys) are basically the same and since pop producers stick mainly to major/minor how do they continually come up with new stuff?
you could venture into weirdland, even if just for a moment. you can go immediately back to normal land, but the journey back will be unique. almost like you get to enter normal land through a different door than before. works every time. there are infinite doors into normal land, but you won't get to use any of them unless you step outside the land for just a moment
