Be careful about using this to justify using AI to write your songs.
It's not about that - at all.

I have yet to see (hear) an AI write that wouldn't get ya shown-the-door if you put your own name on it.
(But the melodies are top-notch - so that - using the melody - could be happening. You still have to be capable of a pro-level lyric to put on top of it.)

This is about production. Mostly demo production.
I sincerely wish I'd had SUNO for production while I was in Nashville. Demos (in the 90's) ran $400 a pop (for truly "competing" demos).
And when everyone is writing multiple songs a week, SUNO must be a godsend (demo production-wise).
