Billboard.com has put together a list of The Top 24 American Idols of All-Time, which was compiled by crunching some numbers regarding their post-"American Idol" successes.
--Things like album sales, digital track sales and radio plays were taken into account, although the specific methodology . . . assuming their was one beyond simply adding everything up . . . is unclear.
--KELLY CLARKSON came out on top. She's sold 10.6 million albums, 15.9 million tracks, and has almost 4.3 million radio plays. Here's the Top 10:
#1.) KELLY CLARKSON . . . winner of Season One
#2.) CARRIE UNDERWOOD . . . winner of Season Four
