I do like songs where a story is told beyond those "fuck you - suck you - lyrics".
And if at some point AIs are better at expressing emotions and telling stories... then that should be an incentive for the human beings among the lyricists.
And a song longer than 8 minutes - my god - is a rarity these days. Too many either have little to say or don't hold out... Seems to be a job for AI already.
