Awesome Covers of Awesome Songs

Looking passed the big groups like the Black mages who have done this and instead turnign our attention to YouTube, you can find some pretty cool covers of great songs just by random guys.

For instance:
YouTube - Final Fantasy IX - Terra

And an epic theme that isn't brought up much gets a great cover:
YouTube - Live Soul Reaver 2 theme (Ariel's Lament) by Between The Zones

A friend linked me to this a while ago
Suteki da ne from Final Fantasy X

UK-based band The Red Wings do some rather nice material, but I'm mostly partial to Soniclang's reimagining of all the songs from episode 1 of DOOM :D

These are nice, but I like Katethegreat19 better.
