"Actually there’s some interesting problems here because a huge part of music marketing is in a visual medium, like a poster or album cover. It is literally impossible to include a clip of your sound."

The term you are looking for is 'aesthetic'.

And indeed.. music is far more than just a sound or whatever simple thing one tries to boil it down to.

Im convinced many (especially here) really dislike that - they want it just be a case of typing in a few things in an LLM and bam... there you go. They have zero clue about the nature of the economy, what's really going on in various markets etc etc.
