Shelton credited Conley with giving him hope when he was trying to get his start in country music.
"I always loved Earl Thomas Conley, but it wasn't until I was about 18 that I really started to appreciate what a great singer he was," Shelton told PEOPLE. "He has a song called 'What I'd Say' that really takes me back. I'd listen to that thing a million times, just by myself in my studio apartment in Nashville, just trying to sing that. I wanted to sing like him, because I knew if I could, I maybe could make it one day."
