I suppose I genuinely sympathize with both of them. Rihanna went through a public, awful domestic violence incident that she's clearly tried to work through in darker, angrier music. It's not very good music, but it does seem to have been helpful for her. Eminem may be in recovery from substance abuse, but that doesn't mean his anger's gone.
But this just feels incredibly self-indulgent. Eminem's slow. Rihanna's autotuney. She's singing about liking to get hurt, and he's rapping about the indistinguishability of hate and love. Emotionally and artistically, it's both of them giving into their worst impulses, and expressing them at the low end of their respective talent ranges (though I think Eminem's is a lot wider than Rihanna's, for what that's worth). It'd be super-depressing if this gets huge, though it probably will.
