Why do we like this?

We're suckers for anything by Deadmau5 or The xx. You don't need to call us out on it. And we know that mashups of the artists are dime a dozen. But this one is special. Not only is it the first I've seen that brings the two artists together, but it does so in such an acoustically pleasing manner that we think we'd be foolish not to share it with you.
