In Eurovision, sometimes a country receives 'Nul points' which means that they get a grand total of 0 points, you have to name the song that received 0 points between 2000-2021. Good Luck!

SF is Semi-final, GF is Grand Final, 50/50 is televote/jury
When there are two names mentioned the first name will be written.
