The use of religious themes in music that is otherwise regarded as illicit has sparked controversy over the validity of the religious messages expressed through the music. Some Christian listeners hold that "rap music, because of what it inherently communicates, is incompatible with the Christian Gospel", and attack the use of Christian themes and symbols in mainstream music as being disingenuous. On the other hand, "since the mid-1990s Michael Eric Dyson and others have pointed to some cultural sensibilities shared by Christian churches and hip hop music; namely male privilege, middle-class biases, sexism, and homophobia." Some analysts believe that the suffering expressed through rap music manifests itself in a certain spirituality that can be compatible with mainstream religious messages, although it approaches religious ideas in a much less direct way than most forms of religious expression. "Just as the MC slides into notes and dances around beats, "spirit" is not attacked straight on; it is courageously approached from below, from the margins, from youth, from uncertainty, through the structures of capitalism and mainstream media." Some think that the use of mainstream religious symbols in predominately African-American music has increased the extent to which that music has disseminated through predominately white American culture.
