Eurovision
As if now, I am hearing songs on Youtube videos to remember which artist is for which song. It has been a while. The songs were the following:
You Are The Only One (Russia) 2016 by Sergey Lazarev
Heroes (Sweden) 2015 by Måns Zelmerlöw
Rise Like a Phoenix (Austria) 2014 by Conchita Wurst
Million Voices (Russia) 2015 by Polina Gagarina
1944 (Ukraine) 2016 by Jamala
There are some songs from different countries competing for the top in Eurovision, not just winners, but there are a lot of singers/bands showcasing their performance to their represented country.
You may want to watch the live/official songs to see how they perform. Some used their choreography and less technology. Some are the opposite using a lot of technology and less choreography. For technology, I mean the visuals or the light flashing/optical illusions.
