Tinie Tempah is so incredibly overrated. I'm actually starting to listen to more rap (I used to listen to pretty much none), but I don't find anything he does appealing.
I definitely think Ellie Goulding, Mumford & Sons, or The xx should've won British breakthrough. You've Got The Love should've gotten best single.
Happy for Mumford & Sons for winning best album though. And I'm also happy Laura Marling won best female, even though I personally wish Ellie Goulding would've taken it. Both are fantastic though.
