I've been a fan of Keri Hilson since she debuted the mid-tempo techno pop-soul song "Energy," back in spring of 2008, which didn't fare too well on the Billboard charts. I noticed her strong songwriting skills, her ability to propel a metaphorical story of love, heartache and life's complexities. With her sophomore effort, No Boys Allowed, musically Hilson sticks to her guns and explores her Techno poppish "Knock You Down"/"Return the Favor" roots a bit more with adding a bit more with the slow ballads. Keri's soprano voice can be quite annoying sometimes, as she has the tendency to squawk and come across a bit raspy, but on the majority of her songs, she manages to keep her voice grounded, which makes listening to her that much easier. Though Keri preaches in her interviews about female empowerment and wanting more from her opposing sex, there is nothing motivational within the club story that makes up No Boys Allowed.
