The Billboard Hot 100—America's definitive singles chart—turns 55 on August 4. In 1958, the music company combined its separate airplay and sales charts to create the Billboard Hot 100. (Fun fact: The first No. 1 single was Ricky Nelson's "Poor Little Fool.")
To celebrate the birthday, the company has revealed the 100 biggest songs to have hit the chart. Some are classics by legendary artists (look out for several entries from the Beatles, Elvis and the Bee Gees), while others are mere one-hit wonders ("Macarena," anyone?). They're all topped by the song that gave birth to a national dance craze: "The Twist" by Chubby Checker.
We've listed the 100 biggest songs to hit America's charts below for your listening, and nostalgic, pleasure.
