Drink Me Baby One More Time

LidRock is a US company that embeds CDs in the lids of soft drinks at movie theaters, convenience stores and fast-food restaurants.
The small CDs don’t work in most cars’ CD players, but work in other players.

Now, starting next month, mall fast-food chain Sbarro will start a Britney Spears promotion. For 80 cents extra, consumers can get a drink with a LidRock manufactured mini-CD featuring Spears’ newest single, a video of Spears and Madonna, and a coupon for $2 off Spears’ entire album at Sam Goody.

There’s a hint to the LidRock mini-cd in Britney’s new video already, where you can see for a few seconds the image of a cup of soft drink, in one of the first sequences of the video.
This is likely to be the first official release of the “Me Against The Music” video on hardware digital media so far.
