About the AI generated/Touhou-style song tags

Should these tags be recategorized to become Song tags? Currently, one is General and the other is Meta, but the original song tag is categorized under Song (discussed here). However, I understand that these tags are more like catch-all tags rather than tags that can be used on their own. Especially for the Touhou-style original song tag, I don't think a work would need this tag and not a specific Touhou-style song. I do think it is helpful for organizational purposes however.
Should these tags also become generic song tags like the original song tag?
I think both "AI-generated song" and "Touhou-style original song" should be categorized as general tags. If a work needs a music tag, I think "original song" should be used, with "AI-generated song" or "Touhou-style original song" added as additional qualifiers.
