Prepare Your Mind, Body And Soul For This Leaked Britney Spears Track

Let's take a trip back to 2004, when Britney Spears was in the zone, Nelly was still relevant and Christina Aguilera was getting back to basics.

A little song called "Tilt Ya Head Back" off Nelly's album "Sweat" featuring Aguilera had just been released, becoming a modest hit and supplying middle school you with a catchy hip-hop/pop collab. Behind the scenes, however, the number had been shopped around to multiple artists, including one Britney Spears.

According to producer Dorian Moore, the track was deemed too "urban" for the pop princess, E! Online reports, so Brit's team took a hard pass. Enter Aguilera, whose "Ain't No Other Man" 1940s aesthetic paired perfectly with the vision for the song's music video.

Few have heard the original Spears version of "Tilt Ya Head Back," lost in the archives of pop stars' unreleased demos ... until now. According to E!, a Singaporean radio station played a clip of the track on air, sparking a social media frenzy among Spears fanatics.

Take a listen to the forgotten 2004 goodness below.

Now let's all tilt our heads back together in honor of what could have been.
