I like watching ESC too. I don't really have a favourite this year. If I have to, then Italy and Albania would be where I vote for (since I don't have the vote for my own country XD), because I like when there's a background to a certain song and thereby both sang in own language. Norway this year was also kinda distinct from the rest tho.
If you want some really amazing ethnic performances, I strongly recommend you to watch Armenia’s entries of 2008, 2009, 2010, 2015, 2016 (instrumental), 2017...
