Seconded, my favourite song as well. Loved the darker sound of Humbug, still love the first two albums as well though. Suck it and See was a little bit too ballady and pop for me, still there's a few songs I really like like Library Pictures and Don't Sit Down. I'm just glad they seem to have gone back to a rougher, rawer sound, it seems to be a better direction so far than Suck it and See. It's pretty different from their material before though and I won't know whether it sticks with me until after a few listens.
Haven't listened to their new singles much though, but is it just me or are R U Mine, Do You Wanna Know and Why'd You Only Call..., all very similar sounding tracks? All driven mostly by the bass and drum, guitars doing light lines. All with high pitched backing vocals, which are admittedly very cool, but I can barely tell them apart.
