The Eurovision Song Contest is an international competition with an annual cycle. It was broadcast first in 1951 and was established by the European Broadcast Union (EBU). The host of the Eurovision Song Contest is usually the former year’s winner’s country. So it’s most likely that the ESC 2017 will be organized in Kiev, Ukraine.
Although many participants are newcomers and little known artists, there are always some songs you can also find in the Euro charts. Even if not before the ESC, most songs stay in the European top 40 for quite some time after the Eurovision Song Contest.
Even though, the participating countries decide themselves who represents them at the ESC and how the representative is chosen, there are still some rules according the representatives. The participants have to be at least 16 years old and can only represent one country per year. Yet, it’s not forbidden for an interpreter to represent different Countries in different years. Composers and Songwriters are not considered as representatives, so it’s possible that the chosen songs for different countries share the same roots in the same songwriter. While the music is playback the song itself has to be performed live. There are no limitations according the euro charts, though.
There are also limitations according the songs. It has to be an original song, so there are no cover songs allowed. The song has to be published earliest on the 1st of September of the prior year and must not be longer than 3 minutes. Although it’s possible to shorten an existing song to meet the policy of the contest.
The songs performed during the Eurovision have to be free from political messages and must not harm the image of the contest itself. Even if this rule exists it’s hard to say if a song is politically motivated or not. Is a song asking for “a little bit of love and peace” less politically motivated than a song about the discrimination of minorities?
