“Strangest Love” arrived first; the song was reportedly meant to appear on Britney's 2003 album “In the Zone.”
The second to surface is an acoustic version of “Don’t Keep Me Waiting,” one of the bonus tracks from her 2011 “Femme Fatale” release.
Britney recently wrapped up her world tour, and got engaged to boyfriend Jason Trawick.
