Some countries aren't particular faithful in their first years of appearance if they get off to a bad start. With Belarus it is not like that. The country debuted in 2004 and they have taken part every year since despite some shaky results.
The first three years, Belarus didn't manage to qualify for the final. They had to wait until 2007 where Dmitry Koldun sang Work Your Magic. Not only did he make it to the final, he also finished 6th, which to date is the best result the country ever achieved.
With 14 participations and only five times in the final, Belarus has had some problems finding a steady steam of qualifying entries.
