Lipinski Stole My Catchphrase
This is an INTERNATIONAL competition, with one entry representing Flag/County (and not just a competition like pro-tennis where country of the athlete is just a technicality). It would be right, if each singer presented music and song, in NATIVE LANGUAGE with lyrics and music which represent the country, history, and the ethnic roots of the music.
Well then make a representation to the EBU with your suggestions. I am sure they will be able to use your pointers on their 63 year old TV show that has hundreds of millions of viewers.
Personally, I like that countries have the freedom to choose what kind of song they want to represent them and what language they want to sing their songs in.
