We're always down for a good Britney Spears throwback and thankfully producer Danja aka Floyd Nathaniel Hills has a few up his sleeves!
Danja, who has worked on a number of albums with Brit-Brit, revealed two demos he worked on for the Perfume singer.
The first demo, previewed in the video (below), was intended for her Circus album and the second one for Britney Jean!
Just like Unbroken, these songs obviously didn't make it to the final track listing, but that doesn't mean they aren't as good as her other hits!
The talented producer also unveiled a never-been-heard-before remix to Brit's Hot As Ice track from her Blackout album!
