For Jennifer Lopez, the title of her new album has more to do with her personal life than her music. Sure, “Rebirth” finds her discovering the joys of giving it up for the funk (“Whatever You Wanna Do,” “Cherry Pie,” lead single “Get Right”). But more often than not, she delivers her signature R&B/pop blend. Of course, Lopez being Lopez, she tosses in new twists here and there. “Hold You Down” (featuring Fat Joe) is a sweet tale of keeping it real in these times of red carpet affairs. The sensual “I Got U” weds a Latin undercurrent to a decidedly ’70s soul vibe. The story line of “He’ll Be Back” recalls her tabloid heyday, while “I, Love” is present-day Lopez. The real surprise is “(Can’t Believe) This Is Me,” a power ballad produced by husband Marc Anthony. Here, her vocals soar in, around and over rich orchestral flourishes.—MP
