The argument is not that only designers can design, nor that everyone should design like a designer. It’s to not confuse shopping for or generating generic solutions with the activity of problem solving. Per Alexander, trivial problems, those that can be solved without balancing interactions between conflicting requirements, are not design problems. So, don’t worry and just pick what you need and like!

Presumably you care about the quality of your marketing. Otherwise why do it at all. Worst case scenario, your marketing turns people off to your music, who would have otherwise been listeners.

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.

So you should be really interested in how to capture the “vibe” of your music in a visual medium.

But if you don’t care at all whether ppl actually listen to your music, then yeah you don’t have to deep dive.

just use clipart & templates and move on then, taking your argument to the extreme and skip the AI tooling.
