Singer Jamala representing Ukraine celebrates winning the 2016 Eurovision Song Contest.

Ukrainian singer Jamala's melancholic tune about Soviet dictator Josef Stalin's 1944 deportation of the Crimean Tatars was crowned the winner of the 2016 Eurovision Song Contest early Sunday, an unusual choice for the kitschy pop fest.

Susana Jamaladinova, a 32-year-old trained opera singer who uses the stage name Jamala, received the highest score of 534 points for her song "1944," after votes from juries and TV viewers across Europe were tallied following performances Saturday night by the 26 finalists at Stockholm's Globe Arena.
