One of my favorite genres and favorite bands in that. Hearing the song and being in deep waters with the genre, I thought it's nice that they participate, but dismissed this as not their best song, even among their newest material through which I originally only came to know them, and therefore their chances to win MGP as well. I liked the song, but nothing extraordinary for me.
Then I woke up to realize the fandom is going nuts about it and checked the live performance. Now I understand why, it was impressive.
I dismissed Cha Cha Cha similarly last year after hearing it due to personal bias (it's hard to objectively rate something you're familiar with, as what you personally already enjoy, doesn't still most of the time translate to what makes a good Eurovision entry) and later on due to juries not letting it win (vocals, mostly) although the hype for the song was otherwise obvious.
I think Ulveham will be this year's Cha Cha Cha, not only for me, but for the wider public as well, yet this one has an actual chance of winning, if only Gunnhild's voice didn't crack and nothing extremely impressive came up from the remaining countries (Serbia, Portugal, Sweden, UK and even much of their participants we sort of know what to expect, so...).
We'll see.
