INFECTIOUS LISTEN OF THE DAY: De La Soul, "A Roller Skating Jam Named 'Saturdays'," from De La Soul Is Dead (Tommy Boy, 1991)

WHY IT RULES: The skippity scratches, the nostalgia with a light disco roll--it hurls you headlong into the strobe 'n' swirl of a '70s-era skating rink. De La Soul at their finest.

BEST PART: "No need to talk--look who just walked in!", followed by the opening horns of "Grease." Oh, Mr. Sprinkler!
