Mumble rap (also known as SoundCloud rap) is a loosely defined[3]microgenre[5] of hip hop music that largely spread via the online audio distribution platform SoundCloud in the 2010s.[6] The term implies mumbling, or unclear vocal delivery, used by artists, and it has been used to describe rappers who do not share the rap genre's traditional emphasis on meaningful lyricism,[7] choosing instead to emphasize other aspects of delivery like melody, mood and tone.[citation needed]
While the term mumble rap has been taken as derogatory,[8][9] some have reappropriated the label,[10] and various critics and artists have defended the style as a new phase in the evolution of the rap genre.[11][12][13]
