full_context: Document 1: American Idol: David Archuleta's performance of John Lennon's "Imagine" was considered by many as one of the best of the season. Jennifer Lopez, who was brought in as a judge in season ten, called it a beautiful song-moment that she will never forget. Jason Castro's semi-final performance of "Hallelujah" also received considerable attention, and it propelled Jeff Buckley's version of the song to the top of the Billboard digital song chart. This was the first season in which contestants' recordings were released onto iTunes after their performances, and although sales information was not released so as not to prejudice the contest, leaked information indicated that contestants' songs frequently reached the top of iTunes sales charts.
Document 2: American Idol: Some of the later writers about the show were more positive, Michael Slezak, again of Entertainment Weekly, thought that "for all its bloated, synthetic, product-shilling, money-making trappings, Idol provides a once-a-year chance for the average American to combat the evils of today's music business." Singer Sheryl Crow, who was later to act as a mentor on the show, however took the view that the show "undermines art in every way and promotes commercialism". Pop music critic Ann Powers nevertheless suggested that Idol has "reshaped the American songbook", "led us toward a new way of viewing ourselves in relationship to mainstream popular culture", and connects "the classic Hollywood dream to the multicentered popular culture of the future." Others focused on the personalities in the show; Ramin Setoodeh of Newsweek accused judge Simon Cowell's cruel critiques in the show of helping to establish in the wider world a culture of meanness, that "Simon Cowell has dragged the rest of us in the mud with him." Some such as singer John Mayer disparaged the contestants, suggesting that those who appeared on Idol are not real artists with self-respect.

Document 13: American Idol: Some in the entertainment industry were critical of the star-making aspect of the show. Usher, a mentor on the show, bemoaning the loss of the "true art form of music", thought that shows like American Idol made it seem "so easy that everyone can do it, and that it can happen overnight", and that "television is a lie". Musician Michael Feinstein, while acknowledging that the show had uncovered promising performers, said that American Idol "isn't really about music. It's about all the bad aspects of the music business – the arrogance of commerce, this sense of 'I know what will make this person a star; artists themselves don't know.' " That American Idol is seen to be a fast track to success for its contestants has been a cause of resentment for some in the industry. LeAnn Rimes, commenting on Carrie Underwood winning Best Female Artist in Country Music Awards over Faith Hill in 2006, said that "Carrie has not paid her dues long enough to fully deserve that award". It is a common theme that has been echoed by many others.
