Pop is any music based on memorable melodies, repeated sections (usually, but not always, verses and choruses), and a tight, concise structure that keeps the listener's focus on those elements. Pop as a musical style, however, began in the late '90s and early 2000s, when a pair of major forces began narrowing and focusing commercial tastes. First, the heavy influence of rap and R&B made the pop singles charts more homogeneous than ever. By the 2000s, a parade of varying artists were catering to the mainstream with a similar type of pop music -- artists as diverse as Destiny's Child, Black Eyed Peas, Faith Hill, Maroon 5, Keith Urban, and American Idols like Kelly Clarkson and Clay Aiken.
