This isn't European but on Tuesday I thought I should start following Korean music a bit better being as I follow Japanese music, I might try and follow Polish music more as well and once I heard this I couldn't stop listening to it. The key change at the end is great.

I really like ballads in the Korean language. I also like the video of his performance on Show! Music Core although it's not quite as good because he doesn't sing the whole thing but it's still cool to see a TV clip of it. Also for an ESC related one I've been listening to Joci Papai-Az en apam a lot as well.
