Nation Song Contest 166

As the previous edition's winner, Hypjø, confirmed it was unable to host the 166th edition of the Nation Song Contest, as per protocol the runner-up was offered the honor. Therefore, the edition was hosted by Rahasia-Diati.
Il-Bidu and Kosma withdrew while Riya-Sampetrina returned from break and Solentoya made its debut.
Insomnéa (formerly Zumkotzen) won the edition with the song "Colder Heavens" by Blanco White. Rounding out the top 6 were Meilutya, Emsfrynt, Ujedinjeni Gvozd, Roseland and New Bander State.
Sakuralia returned to the top 10 for the first time since NSC 144.
