Moon (Kanye West song)

"Moon" is a song by American rapper Kanye West from his tenth studio album, Donda (2021). The song includes vocals from fellow rappers Don Toliver and Kid Cudi. The production was handled by West and E.Vax, with co-production from BoogzDaBeast and DJ Khalil. Alongside the vocalists, all the producers wrote the song. It initially only had an appearance from Toliver, however Kid Cudi was included after the album's first listening event in July 2021. Lil Yachty sought the rapper's appearance by reaching out to Vory, who arranged it through contact with West. The song had been crafted by West before Toliver worked on it in 2021, differing largely from the initial recording on the final version. A tender ballad, it features riffs of electric guitar and lyrics from Kid Cudi about reflecting to better himself.

"Moon" received generally positive reviews from music critics, who mostly praised Kid Cudi's appearance. Some reviewers were divided towards the song's presence on Donda being either an album highlight or underwhelming, while a few critics commended the composition. In the United States, the song reached number 17 on the Billboard Hot 100 and number 7 on the Hot R&B/Hip-Hop Songs chart. It attained top-40 positions in nine other countries, including New Zealand and Canada, while peaking at number 20 on the Billboard Global 200. The song received platinum and gold certifications in the US and Canada from the Recording Industry Association of America and Music Canada, respectively. On Halloween 2021, the Sunday Service Choir performed a gospel version with Justin Bieber. Artist Revenue Advocates issued a lawsuit against West for unauthorized elements of "MSD PT2" on the song in July 2024, accusing him of not having obtained a license for usage.
