I was thinking about how innocuous most of the songs are and whether that met whatever the original brief was, so went off to Wiki to try to find out what that original concept was. I was amused to notice that in the table showing the history of the competion it has these captions:

Edition Finals date Year Broadcaster Venue City Countries Winner

'Winner' is the winning country. So the Wiki history includes things like the Venue (do people really care what hall it took place in?) but omits things like .. oh ... the name of the song and the singer.
