Released posthumously in 2009, "This Is It" is a soulful ballad that serves as both a poignant reminder of Michael Jackson's artistry and a farewell to his fans. Co-written by Jackson and Paul Anka, the song features tender lyrics about love and unity, delivered with Jackson's signature emotive vocals. Originally recorded as a demo in the 1980s, it was later released as the title track for the documentary film Michael Jackson's This Is It, which chronicled the rehearsals for his planned comeback tour. With its heartfelt melody and reflective tone, "This Is It" stands as a fitting tribute to the King of Pop's enduring legacy and his message of love and hope.
