This article includes an overview of the major events and trends in popular music in the 2000s.
Unlike many past decades, the 2000s did not see the creation or emergence of many styles, with the exception of a few indie-related genres such as emo,Alternative R&B, and electronic subgenres like Liquid funk and UK funky. Convergence of different styles was one of the more defining features of the decade, as seen with the creation and commercial success of the British grime genre and trap and chillwave in the United States.
Nevertheless, distinguishable elements can be attributed to the decade from a musical point of view, such as the common and mainstream usage of pitch correction software Auto-Tune, as well as the rise of the internet, media player programmes such as iTunes and music and video sharing websites such as YouTube. Also, most songs put less focus on elaborate bass-lines that use bass guitars and bass synthesisers in favour of louder and booming drums, and used even more electrical instruments.
The popularity of teen pop carried over from the late 1990s with acts such as *NSYNC, Backstreet Boys, Britney Spears, and Christina Aguilera dominating the charts in the earlier years of the decade.
Contemporary R&B was one of the most popular genres of the decade (especially in the early and mid 2000s) which was immensely popular throughout the decade with artists like Usher who was named the number one artist of the decade, and also had the most number one songs and the most weeks at number one of the decade. Beyoncé was named the most successful female artist of the decade tied with Rihanna for the second most amount of number one songs of the decade. In 2004, the Billboard Year-End Hot 100 had 15 of its top 25 singles as Contemporary R&B.
