First off, \m/. Now that that's done...I would like for this topic to be a discussion of the many genres of metal, such as Power, Death, Black, Progressive, and many others. Bands of the genres should also be talked about, as well as reasons as to why you enjoy listening to them. Maybe this will allow some of us to branch out, and discover new bands that we've never heard of.
My personal favorite type of metal is Power metal. I enjoy the beautiful melodies with the amazing fantasy backgrounds that most of the songs embody. A few of the bands I listen to for power metal include: Stratovarius, Edguy, Sonata Arctica, and Kamelot. Of course there are others, but these are just my favorites.
Black and Death metal are a close second due to their dark sound. Dark Tranquility and Children of Bodom are my favorites in this genre. They embody the darkness that this genre revolves around, while having a very beautiful sound to go along with it that sets them apart from many of the other black/death metal bands.
