The Solaris Song Contest is an annual competition to be held among signatories of the Sunshine Treaty Organization Pact and other countries in the world. It is based off of the Eurovision Song Contest, a similar competition formerly held by the now-defunct European Broadcasting Union. Its debut contest was held at at Aldebaran, Union of Midway in 2011. Each participating country submits a song to be performed on live television and then casts votes for the other countries' songs. The song that is voted the most will be declared the winner of that year's competition.
