Lady Gaga makes Billboard history with 'Just Dance'

Congratulations to Lady Gaga, who just became the first artist in history to have two songs pass 7 million downloads in the United States! Gaga's debut single "Just Dance" reached the milestone on the week ending September 24th, joining "Poker Face," which is her best-selling song to date.

"That record saved my life," Gaga said of 'Just Dance.' "I was in such a dark space in New York. I was so depressed, always in a bar. I got on a plane to LA to do my music and was given one shot to write the song that would change my life and I did. I never went back."

"Just Dance" was written by Lady Gaga and produced by RedOne, who is currently working on Gaga's fifth album, due out in 2016.

Lady Gaga is Billboard magazine's 2015 Woman of the Year.
