I'm not a fan of it at all... Johan sounds amazing as always but more and more I am tired of Amon Amarth. The vocals are the only thing that kept me listening as long as I did, and I checked out around 5 years ago. That new song is extra cheese for sure, even more power metal than usual.
That song actually sounds more like my friends in Crimson Shadows. Blatant Power Metal with viking growls.
We used to play shows with these dudes. One of their songs had a drinking game, so even if you didn't like Power Metal it was damn fun. haha.
