Top 10 Songs
(2004 - present) was created in response to the growing popularity of paid song downloads and the lack of global digital song charts in the early 2000s. The first Top 10 Songs of the year chart in 2005
was topped by “Hollaback Girl” by Gwen Stefani. In 2005, "Hollaback Girl" was the first song ever to sell over one million downloads in the United States. In 2014, Top 10 Songs included streaming with downloading to determine weekly, monthly and yearly chart rankings.
