around 6 p.m. Saturday, when Jackson's record label, Epic Records, called the program director for both stations, Frankie Blue, who was also a friend of Jackson, and asked him to stop. Blue later recalled, "They informed me of the dangers of playing a song too early." He refused to say how the song came into his possession. Composition "You Rock My World" is credited as being an uptempo post-disco and R&B song with vocal harmonies. The song is played in the time signature of common time in the key E minor, with Jackson's vocal range spanning from the tonal nodes of D3 to G5.
