Tributes have been pouring in for Casey Kasem, who died on Sunday after a long illness.
Ryan Seacrest, who took over as American Top 40 host when Casey stepped down in 2004, said in a statement, "It’s a sad day for the broadcasting community and for radio listeners around the world. When I was a kid, I would listen to Casey Kasem’s AT40 show every weekend, and dream about someday becoming a radio DJ. So when decades later I took over his AT40 countdown show, it was a surreal moment. Casey had a distinctive friendly on-air voice, and he was just as affable and nice if you had the privilege to be in his company. He’ll be greatly missed by all of us."
Carson Daly tweeted: "Long before MTV and the Internet #CaseyKasem made sure you were hearing the best music out there. Peace be to his family and RIP. #Respect"
