There wasn't one. So I made one. I know I'm not the only metalhead here.
Let's get started with a few of my favorites:

[youtube=yRF0cPnw0A0]The Faceless (death)[/youtube]
[youtube=yeMq4_ZyrLM]Soilwork (melodic death)[/youtube]
[youtube=jig05UNCjv8]More Soilwork (melodic death)[/youtube]
[YOUTUBE=YnWAW6s-0UE]Born of Osiris (technical death)[/YOUTUBE]
[YOUTUBE="8h81PggfE8I"]Dream Theater (progressive metal)[/YOUTUBE]
Please watch the above song in its entirety if you are going to watch it at all. It really is a masterpiece. Unfortunately I could only link to a live version because of copyright bs.
