360 owners rejoice! The ending theme from the credits of Portal is now available in Rock Band form! Well, 360 Rock Band form, as the Playstation Store just underwent that pesky redesign and won’t be seeing any new content for a while.

The download is for the John Coulton version of the song, (pictured right) and at the sweet, sweet price point of $0.00, (0 in MS Points) you owe it to yourself to scoop up this 18 MB gem. We can only hope this item stays promotional permanently, but I have a hunch you’ll need to update that wallet if you want a piece of this action in a week or so. It’s there for you right now! The cake is not a lie!
