Defying all probability, there's a song in Gran Turismo 5 which they've forgotten to name. Have a crack at naming it for them and, if your clever title is chosen, you'll have your name lovingly emblazoned across the game's "Special Thanks" section of the credits. You know, the bit people never stick around to read?
The campaign can be found on the Gran Turismo site. We'll let you know if our suggestion, Broom Broom (The Motorcar Song), goes anywhere.
