The song's title is a reference to Cuban leader Fidel Castro, who died within the same month of its release. Prior to "Castro" being released, West was with Gotti in Los Angeles when premiering his "Saint Pablo" record.
Critical reception
Tom Breihan of Stereogum described the track as 'a skittery, synthetic banger' and showed disappointment in West's feature when writing: 'Does a song like this make you feel any better about Kanye West right now? It doesn't make me feel any better about Kanye West.' The FADER's Will Bundy branded it as 'a monster posse cut'.
Commercial performance
"Castro" charted at number 16 on the US BillboardBubbling Under Hot 100 on January 14, 2017, around a month after having been released as a single.
