I confess. I really love mash-ups. Who doesn't? I mean, they are fun, they are witty, they just rock. Especially this one. It's so good! So well done. I could listen to it a thousand times. It's that good.
It's got Come Together and Closer. Which are just great songs individually (well, I confess I'm not quite so much a fan of Closer) and together... Man, that song could get you really really really into "the mood."
