The top 100 singles of 2014, as compiled by Billboard, were led by the song "Happy" by Pharrell Williams in the number one spot. Second was "Dark Horse" by Katy Perry featuring Juicy J, and third went to "All of Me" by John Legend.
Billboard combines radio airplay with online sales and streaming data to compile the list. Williams won Grammy Awards for best pop solo performance and best music video for his single. The singer announced a deal in February 2015 to pen at least four children's books. One book features children across many cultures celebrating happiness.
Perry's "Dark Horse" became the most-watched music video on YouTube in 2014. From February 20 until November 30, the video was watched 703 million times in the year of its release. Perry's Egypt-inspired music video shows the songstress dressed as Cleopatra, among many other references to the ancient culture. The video's producers say it was Perry's idea to do an Egypt set because hip-hop artist Juicy J hails from Memphis, Tennessee.
Singer-songwriter Legend wrote his ballad to honor his real-life wife, supermodel Chrissy Teigen. The artist earned a Grammy nomination for his hit song. Later in 2014, Legend co-wrote the piece "Glory" alongside Common for the award-winning movie "Selma." Legend and Common went to Selma, Alabama, to commemorate the 50th anniversary of the marches that started in Selma and went to Montgomery, the state capital, in 1965.
