Rihanna's seventh studio album is a bit like her relationship with Chris Brown - sometimes on and sometimes off.
He features on the funky groove of Nobody's Business, the track most fans will naturally gravitate towards because it's their very public response to his assault of her.
He unjustifiably comes across as angry and bitter; she is a tad short of convincing.
It's ironically the weakest of her collaborations, which includes a far more touching moment with Mikky Ekko on Stay while Eminem adds a typically bragged-edge to Numb.
There's a musical nod to Goyte's Somebody I Used to Know on Love Without Tragedy/Mother Mary, one of the more intimate and revealing tracks Rihanna has recorded in her career. No apologies needed except maybe a public one from Brown.
