Audio Illusion.

Was browsing Youtube and I found this. Its very cluttered versions of some classic songs that are played in a way that makes it sound like vocals tricking your brain into think that someone is singing. Truly remarkable.
The third clip("all star") is so damn good. But I recommend watching from the beginning since its can be hard to get into.

Yeah, thats the only one I didn't get. Mainly because I have never heard the original.
