"Blood on the Leaves" presents his thoughts on how fame can cause the destruction of relationships, while making comparisons of contemporary times to the lynching of African Americans in the United States during the pre-civil rights era. West delivers his vocals through an Auto-Tune processor, like on his 2008 album 808s & Heartbreak. It contains samples of both singer Nina Simone's 1965 rendition of Billie Holiday's song "Strange Fruit", and "R U Ready" by the duo TNGHT, who co-produced the track. - Wikipedia
