I just saw the Gears Of War commercial with the Mad World cover performed by Gary Jules. I'd never heard it before and wow, it completely blew me away. I wasn't around in 2001 (travelling with my wife for four months across europe) so I missed Donnie Darko completely. I really loved the original and as much as I hate to say it, the cover just felt more right.. hairs-on-the-back-of-the-neck-sticking-up kinda right. For any other fans of the 80's and/or subsequent covers..

Great song, its still hanging around the radio here, despite being from a several year old, little known flick.
