They should change again, it's been like a decade. I know they're gonna stand up and say you just want us to make Hatebreeder 2 or Follow the Reaper 2. Well why not, but it doesn't mean fans care about neo-classical melodies, they can be Chinese or whatever, but the fresh lead melody orientation, atmospheric feel need to come back, and it can be done while keeping the music at least as dark, so why not.
I think one thing is Alexi's vocals have change a lot since 2001 and it goes together more naturally with the kind of Bodom they've done since HCDR. Another is he writes what he likes. Maybe he gave everything he had in the past and doesn't want to go back there.
