You need to have an account to do the survey, so I'll just respond here.
I have my own music server and so don't use streaming services. Therefore, I have no issues with ads or audio quality. The music in my library is tagged, and "focus" is one of the tags. I have an auto-playlist that just randomly plays tracks that have that tag. When I add new music to my library, I also add the tags.
It works extremely well for me. Zero friction and I always get the music I want.
