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.
