Britney Spears' fans were overjoyed over the Christmas weekend since there were at least two songs leaked from her vault. One is a never-before-heard song called "Strangest Love", and the other is entitled "Don't Keep Me Waiting".
The former song is a love ballad which is rumored to be a leftover production by Guy Chambers from Britney's 2003 "In the Zone" sessions. Meanwhile, the latter is a stripped-down version of her "Femme Fatale" bonus track.
Britney released her latest studio installment in summer this year. She quickly followed it with a lengthy tour which covered big cities in North America, Europe and South America. She just wrapped up the traveling show on December 10 in Puerto Rico.
The tour is ranked at No. 19 on Billboard's Top 25 Tours of 2011 by pulling in around $37 million from a total of 396,000 attendances and 39 shows. It helped her net an estimated profit of $10 million and placed her at No. 10 on Forbes' "Top-Earning Women in Music" list along with Alicia Keys.
