Some Wolfheart and Havukruunu songs would be great.
Wolfheart: Aeon of Cold, Horizon on Fire, The Hammer, Ghost of Karelia, Boneyard
Havukruunu: Pakkanen, Myrskynkutsuja, Pohjolan Tytär, Kunnes Varjot Saa, Valhallan Portit, Jo Näkyvi Pohjan Portit, Uinuos Syömein Sota, Tuuletar, Verikuu, Unien Havulinnaan
Please try at least some of them.
Sorry for requesting so many haha, just a very big fan of these bands and would want to play their music on Rocksmith
