> I believe a big reason this song blew up on social media was that it was misleadingly hyped as an "AI-generated song". I expect many people thought that AI composed and recorded the (reasonably idiomatic) music and lyrics.

IIRC, I read that in the 70s many people thought Popcorn by Hot Butter was also written by a computer, but it was just played on (analog) synthesizers.
