Agreed. I use brain.fm (no affiliation) and have found it great for focusing. While I ride around the city on a bike or euc, I find faster pace music great for getting in the zone / flow state.

For the latter example, I wonder how much of it is though neaural networks wired together fire together. In essence Ive always listened to music while riding so it feels right and known, what if I had ridden all this time without music, would I be better? I don't know.
