It's blasphemy to compare Days to Hatebreeder. It's a filler song for me. I don't understand why it should be catchy. I never liked this thrash stuff. COB is not supposed to be this invalid and simple. It doesn't feel like the cover art at all, there's just a couple bits where they added snow rain and even one orchestral hit. It's too restless as opposed to being epic and catchy. I'll be skipping this one.
Bodom Blue Moon is cool. Badass riff, some atmosphere, electricity and a cool chorus melody. Baseball bats under a bridge with moonshine.
