A lot of them are pretty crappy quality and listening to them kinda hurts your ears, but a lot of them are really good.
Imagine a demo/acoustic version of IKYWT. That'd be amazing... I wasn't much of a fan of the Treacherous or Red demo from the bonus tracks on Red, but the State of Grace acoustic one was good. It would have been nice to get a stripped down version of IKYWT on the side, even though the dubstep version is great for blasting in your car and getting weird looks from people next to you at traffic lights.
