I miss the old Eurovision up until 1997 where all the musical instruments used in a song had to be on stage and voting was carried out by an internal jury. I.e. it was a song contest, not an act contest.
Since then I don't recall any song ever being played that I really liked, i.e. something that I would still like to be played on the radio.
Also, for what's suppose to be the best song in Europe, when was the last time a Eurovison winning song topped the charts for several weeks?
In my opinion, the Eurovision song contest final should be changed to one of the following:
1 - All performers on stage must at least sing or play a musical instrument.
2 - Run the song contest in two stages, maybe across two different days. In the first stage, all the songs are played without the performance being shown (e.g. play the rehearsals, with just the song info and how to vote shown on screen) with the voting lines open after the last song is played. Then run the second stage exactly like now, but with the voting lines closed.
3 - Introduce a second voting line, so people can choose their favourite act, then choose their favourite song. The Eurovision winner will be the one with the best song and another trophy will be awarded to the country with the best act.
