Eurovision Song Contest 2010
For the Eurovision Song Contest in 2010, Bulgaria decided not to use the multi-heat selection system of previous years and select their artist internally. A panel of 51 music experts voted for a number of candidates; Kostadinov was the winner with ten votes, followed by Poli Genova with seven, and Nora in third place with three. Other artists in the running were Slavi Trifonov, Maria Ilieva, Lili Ivanova, Elitsa Todorova and Stoyan Yankoulov, the 2007 Bulgarian representatives.
At a national final, Kostadinov performed five songs written especially for him, in five different music genres ranging from ethno to rock. The winning song, selected by televote, was "Angel si ti". It was performed in the second semi-final on 27 May 2010, but did not progress to the final.
