The Eurovision Song Contest is a popular contest held every year in May among European countries that are members of the European Broadcasting Union. Each one of these countries submits a song, then other countries vote for the most popular song.

The contest is famous for its kitsch music, crazy and wacky performances, misuse of special effects, as well as for the political nature of the votes.
