Happy Monday, y'all! It's been a truly, positively Glory-us weekend, am I right?

While Britney Spears' ninth studio album is just days away from officially hitting shelves (August 26, patience darlings), there's even more for us to discover from the back catalogs: it's Britmas, indeed.

Over the weekend, some eagle-eyed member of the Britney Army spotted an unreleased Britney track in the Spirit Music Group catalog called "Instant Dejavu."

The song, which was registered in 2003 around the same time she was recording and releasing her fourth studio album In The Zone, was co-penned by the immensely talented Rick Nowels, who's done everything from Belinda Carlisle's "Heaven Is a Place on Earth" to Madonna's "The Power of Good-Bye" to dozens of tracks for Lana Del Rey, including "Young & Beautiful" and "Summertime Sadness."

Singer-songwriter and former New Radicals frontman Gregg Alexander also as a co-writing credit, who's penned everything from Michelle Branch and Santana's "The Game of Love" to Sophie Ellis-Bextor's "I Won't Change You" — and in fact, this one even sounds a bit like a disco-y Sophie song from her earliest solo years. Or maybe even some throwback dance floor fever from the disco diva herself, Kylie Minogue? Or Dannii?!

"When I'm making love to you, oh yeah! / You give me instant deja vu, oh yeah! / Don't be afraid to show it," she cries out before the euphoric dance beat and bright piano melodies kick in.

"When it's real love, it's the best drug / This is real, don't be afraid to show it!"

"Dejavu" sure doesn't sound much like anything off the vibe-heavy In The Zone (or anything from any Britney album, really), but it's nonetheless an intriguing glimpse at one of the many directions she was dabbling in during one of the most creatively inspired eras in her career. It's really, really vintage and cool, to quote the Holy Spearit herself.

Oh, yeahhhhhh!
