Though Lea Michele has found success on television and Broadway, her transition to pop diva-dom poses challenges. That said, "Cannonball," the single from her forthcoming debut, Loud, shows promise. As a self-esteem anthem, it sounds like a more generic take on Katy Perry's excellent "Wide Awake." Still, Michele is a likable and impassioned vocalist. She is more mannered than her peers and loosening up may aid her delivery, but she also sounds committed to the material, rising through the sleek production. "Cannonball" is not a masterpiece, but it's sturdy pop and shows that Lea Michelle has lots of potential .
