Easy listening in my experience is production music for lobbies and non-spaces (places we go through but don't exist in, like luggage claim areas). It's part of the social science of keeping people calm when they have the stressor of not being where they want to be or are supposed to be.

LoFi in more recent experiences are similar -- music you can study to, or research to, or otherwise focus on other tasks -- but are usually qualified by being also part of another genre (say metal, or classical or blues or retrocore or cyberpunk).
