I haven't touched a "Gran Turismo" since it was the thing to play on PS One. But I absolutely, positively had to download the copy of "Gran Turismo 5: Prologue" that Sony sent me for one reason: I'm a Weezer fan.

The band hasn't been that great since "Pinkerton", but once a fan, always a fan. When I found out Weezer contributed "Automatic" from their upcoming album (it's actually a remix of that yet-unreleased song) to "GT5: Prologue," I had to check it out.

The result: I've so far put over two hours into "GT5: Prologue" -- earning gold trophies in almost every "C Class" race -- but haven't heard "Automatic" playing over my speakers. There's no sound test, so I have no choice but to keep racing. Good thing "GT5: Prologue" is so gorgeous to look at.

Ever played a game for a reason completely unrelated to the game itself?
