Unlike previous seasons, contestants whose performances not considered good enough were given a second chance in the second round.They lined up on stage in groups of 10 and each sang a short segment of a song "a cappella." After each group had finished, the judges cut those they felt not talented enough. In the final round, all the remaining contestants performed individually a song chosen from a large list of songs provided accompanied by the band and three backup singers., much to the complete disbelief of Harry, Jen and Keith.
Another auditioner who gained some public attention was Renaldo Lapuz who sang his own composition "We're Brothers Forever" which he wrote for Simon Cowell.
He was later asked to return to perform in the finale.
This year the process was altered slightly to ensure that no talent would be prematurely dismissed.
The contestants were allowed two performances before elimination, and the group round was removed.
It was later revealed that his non-selection resulted in serious rift between Simon Cowell and the show producer Nigel Lythgoe.
David Cook (born December 20, 1982 in Houston, Texas, 24 at the time of the auditions and 25 at the time of the show) is a native of Blue Springs, Missouri who auditioned in Omaha, Nebraska with Bon Jovi's "Livin' On A Prayer".After each performance, the judges decided whether or not to cut the contestant.By the end of the day, only 50 contestants remained.Cook's interest in music began early in life; he received his first guitar at the age of 2.He formed a band while still at high school called Axium which was chosen as the best band in Kansas City in 2004.The Hollywood week took place at the Pasadena Civic Center in Pasadena, California, over a period of five days.
