"More 'funkier'" is technically improper English.... Just pointing that out; you could've just said "funkier".

Sorry, I'm a grammar geek, lol, it really doesn't matter, though.

Anyways... I think "Get Lucky" is the funkiest, but that's the only song out of those three that I don't have on my iPod. It got overplayed way too fast for me to even remotely enjoy it.
