Well done on coming third!
This is one of the most enjoyable songs I have heard in the last couple of weeks.
The first minute, the piano driven piece, was lovely. For me, I couldn't stop thinking of Russian aristocracy dancing in a grand hall before 1917. After that things get darker, the outbreak of war and the realisation that not all is well.
I have been reading a lot of Ken Follet recently so that's perhaps why I got that imagery from the piece.
As I said, I really enjoyed it!
