This may not be her best album vocally, and I assure you it is not, but as of soul, it's a terrific effort. The pop tracks have lyrics of a great depth, and they hardly ever bore you. My favorite track is Side Effects, a true invitation for women to cry out loud, and I'm sure they will, because like most of the successful tracks here, it invites you to feel something, to experience the vocals and the up/mid/slow tempo beat, and you do without a second thought. I recommend E=MC²! It's gripping.
