Ludacris' 'Battle of the Sexes' a hip-hop lovefest

Few rappers understand balance better than Ludacris, and "Battle of the Sexes" (Disturbing Tha Peace / Island Def Jam) proves it.

Not only does Luda know when a song needs an R&B crooner or a female voice, he knows when he needs to speed up a flow or rough up a rhyme. It's that combo that makes "I Know You Got a Man" sound fresh, that makes "Sex Room" with Trey Songz a success and makes the Tiger Woods-inspired "Sexting" so funny.

He also knows when the straight-up macking single "How Low" is needed.

LUDACRIS: "Battle of the Sexes"

THE GRADE: B

BOTTOM LINE: More a hip-hop lovefest than a battle
