Wow, I feel privileged that for once I'm not on the receiving end of regional exclusivity. The only performances worth watching are Florence's, perhaps Coldplay's and Adele's (despite not singing Set Fire), plus 21 returned to the top of the album chart.
And yup, I remember. Homewrecker is certainly an interesting song. The spoken verses remind of something, but I don't know. But the chorus is pretty nice. Despite not being totally enthralled by her music (actually, Homewrecker's just got to a good part) I really appreciate that she has a big and ambitious vision for her work, unlike most other mainstream British acts. And Madonna.
By the way, I was searching for this for ages after I heard it and fell in love with it, but this is A Paradise (Coldplay) remix. It's so euphoric, it's beautiful. If you want to miss the dancey rubbish, skip to 0:55. sooooooooooooooo good.
