Timbre and genre are very important things. The remix doesn't need to be as good as the original since it's way better suited to be mixed in an electro swing DJ set. The different context creates an entirely new niche in which the original has no place.
Disclaimer: I googled for something random and sifted a bit through the results - not a fan of dubstep remixes, so I chose electro swing instead :)
