Anyone else love this as well? Included in the Chaotic Extended Play, she had the dance pop thing going on before Kesha, Gaga, Charli XCX came along. That's why I think it's such a forward thinking song and ahead of its time.

Anyone know which album this was intended for? I've always thought The Original Doll as the sound is too dancey for In The Zone.

I love this song a lot, its so before its time, Britney used to be a huge trend setter back in the day, hopefully she'll reclaim that title.

That's what I thought as well. In The Zone and Blackout were massively ahead of its time. With the whole Euro/Dance pop thing she had going on before any of the current female pop stars now started.

I'm hoping her next album will be something like ITZ or Blackout, as in ahead of its time, something new and not as dated or generic sounding as her last record.

I really love this song and I think it was for ITZ but it could have been for Original Doll or Blackout as well. Many people think it's unreleased, but they don't realise it was actually released on the Chaotic EP. I have the EP and I reckon it's the closest thing we'll ever get to Original Doll Still, at least we got the amazing Blackout instead. I consider Blackout and ITZ to be her masterpieces and probably her most innovative albums. Britney (third album) is also important as it was the first era where she was starting to get rid of her teen pop image.

I suppose even albums such as Femme Fatale set trends in a way, it was the first time I had ever heard dubstep properly incorporated into a pop song, of course she did that on Blackout as well with Freakshow but back then I must admit I had no idea what it was!

Exactly. Inside Out is a very dubstep-influenced song and even How I Roll has elements of it. I still think Femme Fatale is the poppiest album she's done since her early days, but it's more dance-pop than teen pop a la BOMT (the album) and Oops I Did It Again. I think Blackout is probably the one that set more trends than any other Britney album, but that's just my opinion

You know what this song is about dont you?

Well it's supposed to be about anal sex, but some say it's about an exclusive nightclub
