I'm debating what kind of music I think Adolphian would listen to in his free time. I'm definitely thinking something hard like metal, but do I want something exceptionally hard like this: https://www.youtube.com/watch?v=FoedCng--Rs and this: https://www.youtube.com/watch?v=Ps0MfBG5-Uo ? Or would something lighter like this prog-rock work better: https://www.youtube.com/watch?v=yGc66wTvmVE

Or heck, would he not be into rock and instead be into something like Finnish Folk music: https://youtu.be/hqthspSKZV8 ?

I need a second opinion! He started life as a self insert many years ago, and though he's evolved past that, I wouldn't want his musical tastes to be anything I wouldn't listen to. And I think music taste is as important to a character as anything else!
