After 11 years on the air, American Idol grads have spawned many dozens of original songs. Who ranks highest? THR's sister publication Billboard (and Idol Worship's own Fred Bronson) crunched the numbers to come up with the top 100 Idol singles of all-time.
Leading the list is original Idol Kelly Clarkson, whose songs take the top two spots and 16 others elsewhere in the top 100.
Season four winner Carrie Underwood is the best-selling Idol in the U.S. (Clarkson is tops internationally) with more songs on the Idol 100 than anyone -- 20 in total.
"The success of Idol is even bigger than Clarkson and Underwood," writes Bronson. "The franchise has produced 379 No. 1s to date, counting all national and domestic charts compiled by Billboard. So far, 68 finalists from the first 11 seasons have appeared on the Billboard charts."
