Someone pointed this out, and I have to agree, the guitar riffs sound harmonically similar to Daft Punk's 'Get Lucky', which adds that sexy subtle funk essence to this already banging track.
In the least creepiest way possible, I've been keeping an eye on these guys ever since they released their first single 'Higher' a couple months back. It hasn't been long, but they've really been experimenting with their styles.
I'm not sure about the rest of you, but I think they should stick down the funk and r&b route just a little while longer.
