Well, I kind of borrowed this wording from the description of your genAI experiences ("intellectually interesting").
I feel that it's nod a bad word to describe qualities of music, although it's a bit nondescript. Sure, music can be interesting, but still unpleasant etc.
But "interesting" means (to me) that the music makes you want to listen to it again.
Music doesn't need to sound pleasant. Or angry. Or sad. Or "abstract" (an oxymoron when it comes to describing a sound, still widely used).
Music is communication.
And just like it's a novelty and sometimes useful or entertaining to use ChatGPT, it's a novelty and sometimes interesting to use Suno.
That's pretty much it for me.
The magic of prompt => non-text media is also interesting, sure.
But not interesting anymore to me as art, at least not without being part of a bigger whole.
Good early example for this would be "Headache - The head hurts, but the heart knows the truth"
