This hasn't been #1 in the UK yet?!! I'm very surprised.
It's been huge stateside and even got the treatment from Glee before the song was known.
I really like it even though I can barely hear Janelle on it

Have you thought it might be because it hhasn't been released yet. Heard it for the first time yesterday and thought it was very good.

I find it pretty average tbh and the chorus is totally lifeless.

It's not even out in the UK yet.
Does anyone know the release date?

It's going to be released in May, but I think they might bring forward the release date.

It's not been #1 yet, but I'm 99% sure it will be #1 soon when it gets released.

I completely agree with what you said about Janelle, she is barely audible. The live acoustic she did with fun of this song is a lot better.

Oh sorry, I forgot that we get new music released ages before UK now
