This list is based utterly on personal preference and is totally subjective.
I'll try to focus on individual songs and limit myself to choose one song of each artist.
I'm also not an avid writer, so it means that most of my "short comments" will be made of things like "this song is great" and "this song is amazing".
And yeah, most of things in this list are made of metal and pseudo-metal stuff.
1. Primordial - The Coffin Ships
I don't have words to explain my love for that song. Catchy riffs, great lyrics and a stunning vocal work that makes that song my favorite song ever.
2. Morbid Angel - God of Emptiness
Love that one since it's stunning "lies!" at the beginning until it's devilish clean chant at the end.
3. Nightwish - Ghost Love Score (Live) (2012 version with Floor Jansen)
