Just for the record, my favourite - and the one I voted for - was the Croatian entry. Nicely understated usage of the circle of fifths in the verse (note to non-musos: I'm talking about the start of the song; compare what you hear to the harmonic structure of the verse of "I Will Survive" - that's the circle of fifths). And DJ 75 Cents was rockin' on the gramophone deck. :o)
ETA: I've found the pop video for it. It takes place mostly in trams.
