According to this article
Baseball fades into the background over the course of months rather than demand that we drop what we are doing and Take Notice. It is the soundtrack of the summer. No, not even that. Itís the score. An accompaniment which complements our days and nights but which is unobtrusive and fits into the action rather seamlessly. Something the presence of which we rarely actively consider but whose absence would be jarring. It isnít a loud roar, but a steady, comforting hum that maintains no matter what else is going on in our lives.
And thank God for that, because our lives can and often do carry plenty of drama and intensity of their own sometimes. A lot of times, actually. We all just need to relax a bit.
