His website says he is able to remember music after hearing it only once. It describes the collection stored in his mind as comparable to an extensive jukebox, encompassing R&B, rock, jazz, Mozart and Chopin.

Following his victory, Lee appeared in America’s Got Talent: All-Stars and America’s Got Talent: Fantasy League. His five released singles consist of “Change,” described as a bluesy pop-rock track; an official recording of “You Are The Reason”; and three other titles—“Hello World,” “A Song For You” and “Journey of You and I.” “Change” is the most recent release.

At age 27, Lee used his YouTube channel for covers, original music, concert footage and vlogs. He also made seven episodes of “Kodi Tries,” in which he attempted activities including clay sculpture, finger painting and a blindfolded Jenga game with relatives. In April 2024, he partnered with Billy Footwear on a signature shoe series called “Kodify.”

Though he had not entered the pop charts, Lee had built an audience of 528,000 Instagram followers and 438,000 YouTube subscribers. Multiple uploads of his America’s Got Talent appearances had accumulated more than 73 million views. He also maintained an official website and accounts on Facebook, Instagram and YouTube for his music and updates.
