The seventh and eight episodes were about the guys in Hollywood. The first round was a round in which the guys solo without any music accompaniment and after the first cut , they were arranged into groups. The group rounds was where many stumbled as they had only 24 hours to prepare for their songs. However there were a few incredible performances too - most notably the first one - a cover of " Somebody To Love".

Generally the judges were right about most of the cuts. For example, the cases of Lazaro Arbos and Kayden Stephenson who both had sad back stories. Kayden was not quite ready yet, whereas Lazaro had the potential to go all the way. However, the judges may have been a bit too lenient in letting so many to go through the next round even though they have forgotten the lyrics.
After the group rounds, were the solo rounds with music accompaniment. 28 singers were picked from there and out of those only 20 will carry on after next week.
