Nuška Drašček, the winner of last year’s Slovenia song festival, introduced us into this night full of music. She reminded us again of the song Tak dan (Such a day). The singer Nuša Drašček and TV presenter Mario Galunič guided the audience in front of the television and radio through the evening, and they also recalled the memory of some evergreen songs, such as Ljubljanska ulica (Street of Ljubljana) by Majda Sepe, V Ljubljano (To Ljubljana) by Marjana Deržaj and Lastovka (Swallow) by Elda Viler.

The festival ended as a mini-anniversary, because it has passed 20 years since they reopened the festival in 1988. The performers were: Katrinas, Eva Černe, Alenka Godec, Anika Horvat, Darja Švajger, Nuša Derendain Marko Vozelj, who were also the winners of the previous Slovenia song festivals. This is a festival of Slovenian entertainment music with a 56-year long tradition. It started back in 1962, when Stane Mancini ended up being then first Slovenian song festival winner with the song Mandolina (Mandolin), and the festival ended in 1988. RTV Slovenia revived the festival in 1998. In 2015, the festival became a part of the Days of Slovenian popular music for the first time since the festival reopened. This year it was yet again organized independently.
