Cowell lauded it as Allen's "best performance so far." Allen subsequently received a signed record and other gifts from the original artists, Glen Hansard and Markéta Irglová.
On the second Top 7 show, Allen brought back the guitar for the fourth time and performed an original, acoustic version of "She Works Hard for the Money", complete with bongo drums and the band on stage.
After winning Idol, Allen made his Billboard Hot 100 debut with five songs charting within the top 100.
His coronation single "No Boundaries" debuted at number 11, followed by "Heartless" at number 16, "Ain't No Sunshine" at number 37, "Apologize" at number 66, and "Falling Slowly" at number 94.
On June 7, 2009, Allen performed the National Anthem at Game 2 of the 2009 NBA Finals to a packed house including Adam Levine, Jack Nicholson, Rihanna, Paula Abdul and Leonardo Di Caprio.
Following the performance, which was described as "executed to perfection," Kris Allen was released on November 17, 2009.
Allen's second major-label album Thank You Camellia was released on May 22, 2012, and the lead single "The Vision of Love" was released March 26, 2012.
Nearly 100 million votes were cast during the finale, setting a new world record for a televised singing competition.
Unlike the previous season, the winning margin was undisclosed.
Numerous sources, including the Associated Press, claimed that the margin "wasn't even close".
Certain commentators labeled the win as an "upset" since runner-up Adam Lambert had received a significant amount of media attention throughout the season and was widely perceived to be the show's front-runner.
