No she shouldn't do "XO". I like the song, but musically and lyrically, it's too lame to even be a top 10 hit anywhere. Just forget about it.

"Drunk in Love" is just iconic. Everything about it>> They really need to push it on worldwide radios, it has great potential..

Anyway for BRITs, I'd say either premier a new single or perform "Drunk in Love".
