Never underestimate the power of soundtrack. The tunes in the ear set the pace, set the mood and sometimes make the day.

Take today, for instance, a gray Tuesday. Ho-hum. But over the weekend I watched a French movie, “The Intouchables,” which featured some of my favorite old Earth Wind and Fire songs. I already had most of them, but after Saturday night I also have “Boogie Wonderland” on my iPod. So that’s what I listened to on the short walk from Judiciary Square to New Jersey Avenue.

Impossible to walk to this song. You bop. You bounce. And you try, very hard, not to dance.

But don’t take my word for it. Listen (and watch) for yourself.

(See what I mean. Even the trees are dancing.)
