Calling all teenage girls! Taylor Swift has just written the girl power, breakup anthem for millennials with her brand new single, 'We Are Never Ever Getting Back Together.'

It's the first taste of her new album, 'Red,' which she revealed will drop on Oct. 22, almost two years to the day after 'Speak Now.' Besides being a massive, singalong song, it's also one of the catchiest tunes she's ever penned. Or in this case, co-penned, since she enlisted Max Martin and Johan Shellback to co-write the song with her, something she did not do with the predecessor of 'Red.'

The song is the ultimate kiss off to the boyfriend that you don't see anymore because he said he needed space, but then he comes sniffing back around again when he wants something, promising to change. Who hasn't been there, ladies? Even our gal T. Swift has experienced that emotion and she encapsulated that universal feeling in an upbeat, empowering song.

The hook, when she declares, "We are never, ever, ever getting back together," is a handicapping, foot-stopping, fist-in-the-air singalong bolstered by the acoustic riff. Who knew that breaking up could feel so good? At most, it's a sonic celebration of strength.

Swift uses the word "like" dozens of times, and has a monologue with herself and then a dialogue with her loser ex-boyfriend in the space of the song. She even includes a couple of conversational bits; it sounds like an authentic recorded chat between her and a friend was used, too.

She drops the statements -"So he calls me up and he's like, 'I still love you' and I am like 'This is exhausting, we are never getting back together, like ever' -- in the middle of the bridge. It's not a new convention -- remember when Britney Spears had the 'Titanic' speech in the middle of 'Oops...I Did It Again?' While that was meant to advance the notion of the sex kitten Brit Brit, Swift twists that very songwriting convention. It's her confessional nature, that accessible BFF-next-door vibe that makes this song one that will connect with the 15-and-under set experiencing their first kiss (and unknowingly getting set up for their first heartbreak.)

This song is exactly why Taylor Swift is the poet laureate of the teen and pre-teen set. No ifs, ands or buts.

It's also Swift at her most poppy, with her "ooh oohs" and harmonizing sprinkled throughout. There's hardly any country twang in the song ... at all.

When she sings, "We are never ever ever ever getting back together," you can envision an arena full of her disciples shrieking the lyrics til their lungs are raw.

All of Taylor Swift's famous exes -- Joe, Jake, Taylor, John -- better run for cover. Taylor's firing on all pistons.

You'll never say never to 'We Are Never Ever Getting Back Together.' The verdict: It may not pander to her country fans, but the pop-leaning, mall-shopper set will relate to this on the cellular level.
