[citation needed] In May 2006, his roommate signed him onto Kochav Nolad, where he won top prize on September 7, besting Maya Rotman and Refael Mirila, singing "Ani Meabed Otakh" (Losing You) and "Nirdam Al Hakholot" (Falling Asleep on the Dunes) with Ninet Tayeb.

After winning the Kochav Nolad title, his remarks about avoiding military service and the release of a song he recorded with Jamus, "Medina Zona, Medina Motsetset" (Whore Country, Blowjob Country), aroused military and public objections.

He returned to the Israeli music business in 2007, releasing "Kashe Li Lo Lehitragesh" (It's Hard Not to be Excited) with Maya Rotman for the fifth season of Kochav Nolad.

After an unsuccessful tour for his debut album, in July 2010, Jacko left Israel and lived in Amsterdam for two years.
