10. Florence and the Machine - Kiss With A Fist
I first heard this way way way back in February when Hannah sent me it. (She also sent me yesterday's song, so she's got a pretty good track record.) It was filed under "good" until the DJ happened to play it in the tent at Lounge on the Farm before Los Campesinos came on (yes, the same DJ who played song 12 in this list) which reminded me of how good it was.
Have Florence performing it live at Camden Crawl.
