If you aren't watching, you are missing out on a very interesting slice of life in Europe. Some great pop or rock or rap songs come out of this. Some songs are boring or generic. Some defy genre but are still musically interesting. Some showcase local language, musical tradition, or clothing. And some are just plain weird, where the "what is happening right now" factor is what you remember more than anything.
On occasion you have some true musical greats--the 1988 winner was none other than Celine Dion, while ABBA won in 1974. Some become nationally famous (1979's fourth place finisher--West Germany's Dschingis Khan--is still played at pretty much any party).
Worth watching and looking up some of the weirdest entries.
