The track's extraordinary success comes 10 months after its initial arrival at Triple A radio last February. Since then, "I'm Yours" has topped the charts at both Triple A and Hot AC, where it has held strong at #1 for a sensational nine weeks and counting.

Mraz celebrated the #1 triumph of "I'm Yours" with a nationally televised performance Wednesday morning on ABC's Live with Regis and Kelly. This follows Jason's recent television appearances on NBC's The Tonight Show with Jay Leno, CBS' The Late Show with David Letterman, and the nationally syndicated Ellen DeGeneres Show.

Last week saw the San Diego-based tunesmith honored with a trio of Grammy Award nominations, including a prestigious "Song of the Year" nod for "I'm Yours." The song also was named in the "Best Male Pop Vocal Performance" category, while Mraz's acclaimed new album, "WE SING. WE DANCE. WE STEAL THINGS." was acknowledged for "Best Engineered Album, Non-Classical" (marking the work of Dyre Gormsen and Tony Maserati).
