"A metal songwriter doesn't subconsciously absorb the entire global corpus of music; they draw from the artists who shaped them"

They also draw from the people around them. The music they hear when they are in public spaces. Etc.

Out of curiosity, have you ever done composing?

Anyway, one can create very shallow songs by hand. One can also give empty vague prompts.

Or one can make a complex music arrangement, manual editing of tracks, have some AI generated mixed in, very detailed prompts etc. If that ain't creative to you, that is your opinion. I think different.
