I think my favorite this year was Daði og Gagnamagnið, but Little Big's was also hilarious and gave me huge Aqua feelings.
I'm in the US, so it's never really "aired" here - we usually watch it online. It's a lot of fun, though! I heard that they did a like... eurovision throughout the years broadcast or something this year, where they celebrated past winners from the previous competitions.
Conchita Wurst is an icon and I love them.
