“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,” Seacrest said in a statement. “He’ll be greatly missed by all of us.”

Kasem, an internationally famous radio broadcaster with a cheerful manner and gentle voice, died Sunday at age 82. He became the king of the top 40 countdown with a syndicated show that ran for decades.

Seacrest, who took over the countdown from Kasem in 2009, said that as a child, he'd listen to Kasem's show every weekend "and dream about someday becoming a radio DJ."

Kasem's legacy reached well beyond music. His voice was heard in TV cartoons such as "Scooby-Doo," where he was Shaggy, and in numerous commercials.
