Listening to it non-stop.

Queen X is back A-M-A-Z-I-N-G !!!!!!!!!!

I wonder if they will now rush out the official version due to the leak?

She has also been trending on Twitter. Song seems be going down really well.

They should do in the US and Canada.

I HOPE they do because in that case, a VMA's performance will be inevitable!! I can't wait until 2013 for Christina's return to the VMA's, it's been 4 years since her last performance!

I agree, they did this P!nk's latest single and that turned out ok. It's only a couple of weeks until the original Voice promo and I'm sure itunes and radio will build up until then and when she performs it, it would rise even more! I think this has #1 smash written all over it tbh

I'm not feeling this at all! I thought she would have learned after NMT.

It seems too overtly sexual, which, considering she released "Dirrty" is saying something, and a bit like she's sold out for commercial success again.

Maybe the actual version might sway me, instead of the demo...

I love this! Super catchy, I was knew the chorus after one listen.

I can't believe that's just the demo! Love it.

Christina has always been overly sexual. Aside from Dirtry. She sang about casual sex buddies on Get Mine' Get Yours, spoke of her husbands big willy on Candyman and Nasty Naughty Boy and on Bionic told us how she loves Sex For Breakfast. This is XTina. She ain't ever any different. Thats why she has the nickname.

I wasn't sure about it at first, but after a few listens, I really like it. Her voice is just immense!

Can't say I know GMGY or NNB, but Candyman seem innocently-fun, sexual instead of "I just wanna **** your body" sexual, and Sex For Breakfast seemed as overtly sexual as Your Body and it was far from single material in my book.

I know Xtina is sexual, but Dirrty was technically about making a party crazy, but they stuck some barely there costume on her and labelled her a nymphomaniac. The other Stripped singles arn't really about sex either. Back to Basics wasn't overtly sexual in it's singles. Bionic was sexual in a lot of it's songs, but in my opinion it didn't suit her. You Lost Me is the only song I revisit from that album..., somtimes Birds of Prey too.

The sexual part doesn't bother me. But I don't see what the big deal about the song is. It seems like more of the usual R&B/dance fusion. It's not interesting to me. But then I've never been a big fan of Christina's shouty vocal style. The only recent song I've really liked by her is Birds of Prey because it has a different trip hop/electronic style, whereas this is more of the same.

It's absolutely AMAZING! I am dying with anticipation for the mastered version now, when does everyone reckon we'll hear it?

She was going to premiere it on 'The Voice' on September 10th, but maybe the plans have changed now that the demo leaked.

Ah! Do we know that this is for sure the lead single? Heard some rumours that it's just a Bionic offcut...

'Your Body' is confirmed to be the lead single. Christina didn't work with Max Martin at all during the recording sessions of 'Bionic', so it's definitely not a 'Bionic' track.

Holy... I LOVE it! At first I wasn't sure, but as soon as the chorus hit I was hooked! I'm on my fifth listen and counting.

She never fails to disappoint!

Agreed. Front page itunes promo WW, it easily can be a big smash.

and if it was it was a very, very poor decision not to include it. This beats everything on Bionic hands down. Love this song.

I am a mess right now. I love everything about the song. Her delivery is flawless

This is immense!! I am rarely so impressed with a demo but I can not stop listening to this!!

for a demo this is great!! I can't believe the video has been shot already aswell. Can't wait to see and listen to this all in HQ

This song vaguely reminds me of I Wanna Go by Britney....they share the same writer and I think the production is similar, but it's an awesome song....just what Christina needed to come out with...

Aaaahhh, I love it!
