The fourth season of Deutschland sucht den Superstar was aired on German channel RTL from February to May 2007.

On 14 March, Bild Online reported[2] about a loud argument between Bund and former contestant Tristan Iser, which happened to have also been filmed by a mobile phone camera.

On 22 April, Bild announced that contestant Max Buskohl quit the competition due to RTL's rejection of his request to let his school band Empty Trash get a recording contract alongside him.

Viewers had wondered about judge Dieter Bohlen's uncharacteristic behavior when he gave an extremely critical review of Buskohl's performance on 21 April.

[5] However, Buskohl's father Carl Carlton told Spiegel Online that his son already made his decision to leave on 19 April but waited until Sunday to make his announcement at request of RTL.

On 19 March 2007 a CD featuring all of the songs from the show and an additional version of If You Don't Know Me By Now by Simply Red sung by all contestants was released.

The viewers' decision in this episode came as a complete surprise,[9][10] as Urio, who was eliminated this time, ranked among this season's best and most favored contestants.

Before the decision, jury member Dieter Bohlen ironically predicted Urio's elimination in what he thought was an April fool hoax.

[11] This was the first theme show to be co-hosted by female host Tooske Ragas along with Marco Schreyl in this season of Deutschland sucht den Superstar.

Being voted out in the seventh theme show, he returned as a replacement for Max Buskohl, who quit the contest by his own will after having serious disagreements with jury member Dieter Bohlen.

[15] He stated in an interview with Der Spiegel that he left DSDS voluntarily, while RTL claims they threw out Max.
