You're not creating music.
It feels incongruous to read that you don't have time to learn a DAW, or an instrument, but you have time to upload to YT, in multiple formats, and compare outcomes between shorts/vids?
Small pockets of free time can go a long ways: putting in 15-30 minutes a day towards learning something new will produce tangible results.
Learning to create music is such a multifaceted pleasure: exploring tooling and mechanics, integrating somatic processes (feeling it!), investigating theory and history, increasing execution incrementally, exploring and expressing emotions+ideas, and maybe, eventually, conveying those emotions and ideas to listeners? What richness!
The Suno->Youtube pipeline feels like an attempt to experience a watered-down version of the conveyance bit, at the expense of the rest.
