"SZA was heralded for redefining R&B with her eclectic influences [on her debut] and 'SOS' takes that range even further. As well as grunge, pop-punk and acoustic guitars, it slinks through rumbling, dirty bass ("Low"), soulful, classic ballads ("Gone Girl"'), chipmunk soul ("Smoking On My Ex Pack"), and much more. In some other artists' hands, that collage could feel unfocused, but under SZA's command it feels cohesive, organic and like every skip into a new genre is completely justified for each track".
