It was a fight to the finish, but ultimately Britney Spears' iconic '90s hit 'Baby One More Time' beat out Lady Gaga's 'Bad Romance' and has been crowned the Greatest Pop Song of the Modern Era!

In the final round, Britney and Gaga duked it out for the title, but only one could prevail as the winner -- and that honor went to Ms. Britney Spears. 'Baby One More Time' garnered more than 57% of votes in the championship round, all thanks to the die-hard passion of the Britney Army.

Over the past month, 32 of the best songs in pop music history have gone head-to-head in March Music Madness. The hit songs were divided up by decade, with eight songs competing in each decade. 'Baby One More Time' beat the Spice Girls' 'Wannabe,' Hanson's 'MMMBop' and the Backstreet Boys' 'I Want It That Way' to ultimately triumph in the '90s bracket. The classic pop tune then faced off against the legendary Michael Jackson -- but showed its staying power when it beat out the King of Pop's 'Billie Jean' in the semi-final round. Of course, it ultimately knocked out Gaga's 'Bad Romance' to win the crown.

Congratulations to Britney Spears! We always knew that 'Baby One More Time' would stand the test of time, and now its new title -- Greatest Pop Song of the Modern Era -- undoubtedly proves it.
