I like Ariadne too. Her song is simple, yet catchy and memorable. I agree that "Goodbye to Yesterday" is better, that is just amazing but I really like "In or Out" as well.
Estonia revealed the 10 entries competing in the first semi-final and I really like Elina's song, she didn't disappoint me. I also like three more but unfortunately, not the rest. Let's hope for better ones in the second semi-final. They are going to be revealed next Thursday.
