Here’s few of my favorites

Kiuas - Across The Snows

One of my favorites from Kiuas as it also contains part where they sing in Finnish :P More popular songs are “Warrior Soul” and “Kiuassault”.

Turmion Kätilöt - Vastanaineet

2 Times Terror - Ikävässä Paikassa (side project of Turmion Kätilöt)

Battle Beast - King For A Day

Egypt Central - White Rabbit

Children Of Bodom - Are You Dead Yet?, also Oops I Did It Again! is epic 😁

Lordi - Devil Is A Loser

Stargazer · Blood Stain Child

Korpiklaani - Tequila

Bring Me The Horizon ft. Babymetal - Kingslayer

Star-Lord band - Zero to Hero (from Guardians of the Galaxy game)

Noora Louhimo is a goddess. What a voice! (The singer of Battle Beast).

I've seen her live and I tell you, she somehow sounds even better?!
