The Top 20 Billboard Hot 100 Hits of the 2000s

In honor of Billboard magazine's 120th anniversary on Nov. 1, we're revealing the top 20 Billboard Hot 100 hits from each decade since the 1960s (for a total of 120 songs).

R&B and Hip-Hop accounted for almost every one of the top 20 Hot 100 hits from the 2000s. There were two exceptions: Nickelback's "How You Remind Me," at No. 5, and Timbaland's collaboration with OneRepublic, "Apologize." More rappers appeared on the list than ever before: Kanye, Nelly, T.I., and OutKast as lead artists, and several others as featured artists.

But R&B singers were the key. T.I. was the only rapper to get into the decade-end Top 20 without the aid of a vocalist. (On "Hey Ya," Andre 3000 served as his own hooksmith.) Jamie Foxx helped Kanye; Kelly Rowland helped Nelly. Elsewhere Mario, Ashanti, and Alicia Keys crooned their way to the top, and Usher struck twice.

A quarter of the songs here involve multiple artists, even more than in the '80s when duets were so popular. Rap and R&B, once distinct, started merging in the '90s -- or even in the late '80s, with New Jack Swing -- and their union proved successful on the charts throughout the '00s. Cross-genre pairings like the one between Timbaland and OneRepublic also became more fashionable.

After ballads ruled the '90s, danceable beats came back in to style. Mary J. Blige had the biggest hit of her career with a rare uptempo track. The Black Eyed Peas got into the top 20 with two pounding tracks. OutKast's "Hey Ya" is another speedy number.
