World music is a term with widely varying definitions, often encompassing music which is primarily identified as another genre. This is evidenced by world music definitions such as "all of the music in the world", "somebody else's local music" or "non-western music". In the classic definition, world music is the traditional music or folk music of a culture that is created and played by indigenous musicians and is closely related to the music of the regions of their origin. The term was originally intended for ethnic-specific music, though globalization is expanding its scope; it now often includes hybrid sub-genres such as World fusion,Global fusion, Ethnic fusion and Worldbeat These terms may also be considered sub-genres of pop music, illustrating that the term world music refers to music that is also classified under other genres.

The term has been credited to ethnomusicologist Robert E. Brown, who coined it in the early 1960s at Wesleyan University in Connecticut, where he developed undergraduate through doctoral programs in the discipline. To enhance the process of learning, he invited more than a dozen visiting performers from Africa and Asia and began a world music concert series. The term became current in the 1980s as a marketing/classificatory device in the media and the music industry, and it is often used to classify any kind of non-Western music.^{[citation needed]}

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
