Everyone get on spotify and listen to this magnificent band. Defined as "post-hardcore subgenre of Nintendocore" or insert other genre here, it doesn't matter as long as it sounds cool which it does. Finntroll should definitely do more songs with 8bit keyboards, listen and learn m9s!
Recommended songs: Horse the Song, The Failure of All Things, Desperate Living, Science Police, Face of Bear.
