The songs themselves have evolved in interesting ways. Diggi-loo Diggi-ley represents the high-point of the nonsense-chorus Eurovision song, designed to appeal to the multi-lingual audience. This lowest common denominator approach produced successes throughout the first thirty years of the contest, including such classics as Boom-Bang-a-Bang (UK), Ding Dinge Dong (Netherlands), A-ba-ni-bi (Israel) and of course Diggey-loo Diggi-ley. (I promise I am not making these up.)
The breakup of the Eastern Bloc and the Soviet Union in the 1990s caused all kinds of problems for the contest (too many countries) but also injected a fresh dose of bad taste. Countries like Slovenia, Estonia and Romania can use odd native instruments to produce Euro-Heritage songs, and also have the advantage of being 10 or 20 years behind the rest of the world in terms of popular music genres.
