Sometimes you have to go back to go forward. 'Unbroken,' a shelved Britney Spears demo from her seventh album, 2011's 'Femme Fatale,' has found its way onto the Interwebs.

The song is a light, electropop baller with lots of blips and beeps, in which Brit's voice is run through tons of synths. She sounds like some weird kitten-cyborg hybrid, in a way that only she can.

According to Idolator, Brit's fans quickly assessed and noted that the song was produced by Fraser T Smith and that it was recorded during 'Femme Fatale.'

Given the fact that Brit's latest, 'Britney Jean,' landed with quite a thud, despite being released in conjunction with the launch of her critically and commercially successful Las Vegas residency, it's not strange that a track from that album and era of Brit Brit's career would escape the vault and hit our ears.

It is posted above for your listening enjoyment. PopCrushers and Brit Army, what do you do you think? Do you love it? Wish it was included on the original album? Should Brit have released this? We've totally been jamming out on it.

Remember, Britney records lots of songs that don't make the final cut. She even recorded a version of Lady Gaga's 'Telephone,' which she famously did not use.
