I ran into a similar thing today, focus@will:

https://www.focusatwill.com/about/

More than specific patterns they offer, I found interesting that they they claim unfamiliar music is better for productivity:

"And the single most important factor to consider when choosing a genre is what kind of music you usually listen to for fun and entertainment when you are not trying to be productive. And then, counter-intuitively, it's best to select the very opposite kind of music when using focus@will. Why? Because your brain gets pleasure, releasing dopamine when it hears music you like and listen to a lot, and music that is associated with good times or strong memories of any kind will reduce the focus enhancing effects when used as a productivity tool."

Unfortunately, I can't try them out because I'm not in the US.

Well, I know it's anecdotal, but this is not how it works for me. Music I enjoy, with lyrics, works pretty well.

I'm trying them out right now. Seems interesting.
