Since Facebook requires you to sign in to embed videos, here's an AdAge story where they have it embedded.

The ad is done by Wieden & Kenedy (W+K for short), who are generally pretty great at fun, spunky clips that entertain and engage (like the "Dance Pony Dance" one for Three.co.uk). This one reeks of a different kind of spunk.

Those "Like"-ing it on Facebook, I assume, are doing so as endorsement of their respective Facebook addictions, the fun music, or what they see as a cool new version of their timesink of choice. Everyone critical of it, like me, are mostly responding to how the advert actually highlights all of the most negative or annoying things about Facebook: the force-fed sensory overload, the head-in-the-phone syndrome, and the narcotic-like nature of being hooked on using it.
