Rebel Heart is the thirteenth studio album by American singer-songwriter Madonna, released by Interscope Records on March 6, 2015. She worked on the album throughout 2014, co-writing and co-producing it with musicians including Diplo, Sophie Xeon, Avicii, and Kanye West. The album also features guest vocals from boxer Mike Tyson and rappers Nicki Minaj, Nas, and Chance the Rapper. Thematically, Rebel Heart represents the singer's romantic and rebellious sides; the ideas grew organically during the writing and recording sessions. Musically, it is a pop record that merges genres such as 1990s house, trap, and reggae, while using acoustic guitars and a gospel choir. Some songs are autobiographical, while others discuss love and Madonna's career. Unlike her previous work, the large number of collaborators made it difficult for Madonna to maintain a cohesive sound and creative direction. The record was scheduled for release in March 2015, and the first single was slated for release on Valentine's Day.
