Friend, you're missing out by applying a too-rigid filter. There's a bright-line distinction to be made between this use of music as a tool for cognitive enhancement, vs listening for valid reasons other than focus.

I'm a musician too, and a lifelong student and appreciator / afficianado of music across many genres. And I spend hours every workday listening to tracks from my "flowstate" playlist -- which tracks are excluded from my taste profile. Other use cases include music appreciation (close attention for pleasure), education / cultural literacy (close attention for analysis / learning), performance (close attention for reproduction, typically broken into segments / fragments), dancing (mixed attention, emphasis on rhythm and physical movement), relaxation (minimal attention), meditation (minimal attention), mood-setting / socialization (mixed attention), etc.

Judging a piece of music intended for one of these categories based solely on whether it's "worth listening to" or "[demanding of] respect" in the context of the wrong category will leave you impoverished in the other areas.

EDIT: P.S. That doesn't mean tolerating muzak! I recommend curating playlists limited to tracks that you can appreciate in a given appropriate, narrowed context. For example, here's my "flowstate" playlist:

-- which bears almost no relation to my favorite artists or the kind of music I make.
