List of countries in the Online Music Song Contest (A-L)

Seventy-eight countries participated in the Online Music Song Contest since it started. Winners of the contest have come from five of these countries (Kiribati, Kyrgyzstan, Portugal, South Korea, United Kingdom). The contest is held in the winning country of the previous edition. Broadcasters from different countries submit songs to the event and cast votes to determine the most popular in the competition.

The number of countries participating each edition has grown steadily, from 18 in OMSC 1 to almost 40 in OMSC 4. In that occasion a record 38 countries participated, while in OMSC 2 a record of just 14 countries participated, making it the edition with the smallest number of participants since the start of the contest so far. As the number of contestants has risen, preliminary competitions and relegation have been introduced, to ensure that as many countries as possible get the chance to compete.

Some countries, such as Canada, the Faroe Islands and the United States of America, have participated in every edition, while countries like Belgium, Colombia and Malaysia have only entered once. Some countries, such as Chile and Singapore, have attempted to enter the contest but withdrew before making a debut.
