Kelly Clarkson can cross another item off of her long list of accomplishments. Arguably the most famous ‘American Idol‘ alumna, Clarkson’s single ‘Stronger (What Doesn’t Kill You)’ off her album ‘Stronger’ became the best-selling ‘Idol’ single of all time, even knocking fellow ‘Idol’ winner Carrie Underwood back to second place. Underwood held the title when her single ‘Before He Cheats’ was released.

As of July 5, ‘Stronger (What Doesn’t Kill You)’ has sold 3,510,000 million copies, and if you feel like comparing, ‘Before He Cheats’ sold 3,509,000 million copies back in 2006. That’s, ya know, a lot of sales. ‘Idol’ winners seem to hold the record for this, because before Clarkson, Jordin Sparks was runner up to Underwood for the same title, with the release of her single ‘No Air’ with Chris Brown. Damn these ‘American Idol’ kids…

Even though Clarkson can take a bow for her incredible achievement, Underwood still holds the crown for most albums sold. To date, she has sold a total of 13,205,000 albums, whereas Clarkson has sold 11,664,000 — not too shabby for either party. BUT! If we were to count the total digital downloads of singles, Clarkson wins that race with a whopping 24,100,000 sold compared to Underwood’s 22,535,000 sold.

This is too many numbers for us. We’re entering into CPA territory here.
