Power metal, for its special energy and "soul" [I don't know how to describe it].
The bands I love in this genre: Freedom Call, Avantasia, Blind Guardian, Divinefire, Narnia, Sonata Arctica, Helloween.
Germany and Scandinavian countries have the best metal bands, if you're a metal fan but haven't tried bands from these countries you're missing out a lot. :yes
I also listen to: alternative rock, symphonic metal, darkwave, neoclassical, some goth rock and deathrock.
Cheyenne: Epica and old Nightwish belong to my favourites too! But there's really no need to know many bands of this genre because they're very similar to each other and copying each other and a lot of them aren't worth listening... but I find specially these two bands really good.
