I'm more into old school heavy/trash/power, but some of those songs sound really good.

Ooo! I'll add them both on Spotify! Love the sound of Considered Dead already.

Only know a bit of alternative and progressive metal. Black/death metal is a little too hardcore for me. lol

I've listened to Immortal, Demilich and Cthe'ilist, but the other bands I've never heard of.

If Opeth counts, all of their albums; if not, probably nothing i guess
