Grew up listening to Casey Kasem on American Top 40 and would host countdown shows in my room pretending I was him. I was inspired by Casey's gift of words to convey emotions and bring music to life over the airwaves. It's an honor to continue his legacy and celebrate 50 years of AT40 this weekend! | Ryan Seacrest
