"Ain't Nobody's Business," Rihanna's duet with her abuser Chris Brown from her upcoming Unapologetic album, has leaked. It is an excellent pop song: sublime, clear, catchy. For its chorus, it interpolates (and slightly alters) an adlb from Michael Jackson's "The Way You Make Me Feel" for its chorus ("Ain't nobody's business but mine and my baby's"), but it's produced more in the style of Steve "Silk" Hurley's remix of Jackson's "Remember the Time." Produced by The-Dream and Los da Mystro, "Business" is a piano house number with a relaxed tempo and string shrieks, it manages to avoid EDM trappings (no drop anywhere to be found!), sounding classic and lovely. This will probably be massively popular, and impossible to ignore very, very soon. Rihanna and Chris Brown are reunited and it feels so cognitively dissonant.
