"Flex your music muscle" for Virgin Digital. Created by Ground Zero. Made by National Televison.
Rant: The thought of 'uncover the hidden items' is not entirely fresh. It was recently used by Stella Artois. But the connection there was weak. Here the connect is stronger. I believe this spot was a viral bomb that got a lot of attention for Virgin.
Note: After you've done your guessing game, I suggest you visit Brainstorm9 for decoding the 50 odd music references in the commercial.
