AMERICAN IDOL COUNTDOWN: 27 Best Selling 'Idol' Singles

So why 27? Because American Idol alumni officially has 27 million-seller singles under its belt. Impressive no?

Of the 27 million-sellers by Idol contestants, eight are by Season 1 champ. That's twice as many as her closest rivals. Carrie Underwood, the Season 4 winner; Jordin Sparks, the Season 6 champ; and the band fronted by Chris Daughtry, who finished fourth in Season 5, have each landed four million-selling downloads. David Cook, the Season 7 champ, has had two.

Clarkson has also had the most consecutive million-sellers of any Idol contestant. She had six million-sellers in a row from Breakaway through Never Again. But Clarkson doesn't have the best-selling song by an Idol contestant - or even the second best-seller.

A few milestones:

• Daughtry's rock ballad It's Not Over, which has sold 2,103,000 copies, holds two records. It's the best-selling digital hit by a male contestant in Idol history. And it's the best-selling hit by any singer who didn't win the competition.
• David Archuleta, the Season 7 runner-up, was just 17 in November 2008 when Crush topped the million mark in paid downloads. That made him the youngest Idol contestant to top 1 million. (Jordin Sparks had already turned 18 by the time Tattoo became her first million-seller in January 2008.) 
• Jordin Sparks is the youngest contestant to top the 2 million mark. She first achieved that milestone in June 2008 with No Air.

The Fine Print: Contestants from the first few seasons of the show were at a disadvantage in making this list because there were no million-sellers in the digital world until October 2005. Songs released before then (such as Clarkson's first hits from Breakaway) have subsequently topped the 1 million mark, but it's harder for them because they peaked on the charts before digital sales really took off.Physical singles were still available in the early years of Idol, so I checked gold and platinum certifications by the Recording Industry Association of America. Clay Aiken's 2003 hit This Is The Night was certified platinum (signifying shipments of 1 million physical copies).

Five other physical singles by Idol contestants were certified gold (signifying shipments of 500,000 copies). These were Clarkson's 2002 hit A Moment Like This, Aiken's 2003 hit Invisible, Ruben Studdard's 2003 hit Flying Without Wings, and dueling 2005 recordings of Inside Your Heaven by Underwood and Bice.
