Need your help :)

So, my friend and I are going to be performing in a showcase in June doing a doubles routine.  We already had chosen Diamonds by Rihanna as our song but we have been thinking we'd like to use a cover or remix instead of the original. We have two that we like but we each have a different pick so I was hoping I could link both of them, and all you Veeners could give us a hand by voting on your picks! It's a showcase, not a competition. If that makes any difference in anyone's choice!    Metal (sort-of) cover by Farewell 2 Fear: http://www.youtube.com/watch?v=9TZZ2uxhI3w Dubstep remix: http://www.youtube.com/watch?v=sJ1mFzMx_CU   Thanks so much :D
