Released in 1982 as the lead single from his Thriller album, "The Girl Is Mine" is a light-hearted, catchy duet featuring Paul McCartney. Written by Michael Jackson, the song combines elements of pop and R&B, with a playful exchange between the two artists as they compete for the affection of the same woman. Its smooth melody and fun lyrics, along with the chemistry between Jackson and McCartney, made it an instant hit. "The Girl Is Mine" was one of the first tracks to preview Thriller, and although it wasn’t as dominant as some of the album’s later singles, it still became a commercial success and remains a classic pop duet.
