Country music singer Marty Stuart said: "People remember the big hits and the visual image of him, but they forget what an innovator he was in the 1950s as a jazz musician. He made inroads for all of us when he did 'I Can't Stop Loving You.' It took country music to places it hadn't been before."
Aretha Franklin, music's "Queen of Soul," called Charles, "the voice of a lifetime." In a statement she said: "He was a fabulous man, full of humor and wit. A giant of an artist, and of course, he introduced the world to secular soul singing."
Dan Aykroyd, who appeared with Charles in the 1980 film "The Blues Brothers," said he saw him perform about two years before his death: "Like the numerous and substantial obstacles he overcame in his life to emerge as the great songwriter and star performer that he was, his final illness only slowed him down. It didn't stop him from sharing his music with us until the very end."
