This may be old news to some of you, but I just stumbled across it for the first time: Yacht Rock, a five-part mockumentary about the heyday of "smooth music."
They hit all the lowlights of the late '70s and early '80s mellowness, including Kenny Loggins, Michael McDonald, Steely Dan, Journey, Toto, Hall and Oates (pictured here in an alley songwriting showdown with Loggins and McDonald), a strongly hormonal Michael Jackson, and, for some reason, Vincent Price.
All the episodes are hysterical, but for maximum effect you should watch them in order. (That means start with #1, for those of you in the back of the classroom.)
(Update: A belated, shamed hat tip to the excellent Stereogum for the link.)
