Andy Grammer played his music on the streets of Los Angeles all the way to the top of the charts. It’s this type of can-do attitude that allowed him to play with stars like Taylor Swift and Colbie Caillat. Plus, he fits the image of a cute, Justin Timberlake-like pop star.

As a younger, struggling musician, Grammer would hook up his amp to his car battery to get that extra juice needed for a great performance. Since then, he’s never forgotten his roots, which is his most attractive quality. His Facebook is riddled with photos he’s taken with fans, and shows how dedicated and appreciative he is of success.
