This spot resembles a Monty Python type of cartoon which, through modern computer technology, has been dragged into the second millennium. What makes it fun to watch a number of times is the fact that, hidden in the bizarre images, are the titles of 35 famous songs. Some of the easier ones are the (tap)Dancing Queen, the White Rabbit, the Rolling Stone, or the Hotel California. See how many you can detect in this playful animation extravaganza for Virgin Digital. Payoff: “Exercise Your Music Muscle.”
