With Friday's much-anticipated release of Janet Jackson's comeback album Unbreakable -- her first LP since 2008's Discipline -- it's the perfect time to look back at the pop diva's 10 No. 1 hits on the Billboard Hot 100. While they all still rank high in our hearts, we can't help but rank them. Here’s our countdown to the very best of her No. 1s.
10. "Doesn't Really Matter" (2000): It's hard to see how this song -- originally featured on the Nutty Professor II: The Klumps soundtrack -- went to No. 1 when true JJ classics like "What Have You Done for Me Lately," "Nasty" and "Rhythm Nation" didn't. Still, this frothy confection was a ray of melodic sunshine after the darker Velvet Rope.
