I too am going to revive this old topic.
I'm working on creating a custom tailored theme song actually, but I've got a couple from the last two years or so since I posted.
Voicians - Inside (circa October 2016):
Circle of Dust - Outside In (circa December 2016):
Tool - The Grudge (circa May 2017):
Fit For a King - A Greater Sense of Self (circa June 2017):
Demon Hunter - I Am A Stone (circa August 2017):
Red - The Mask Slips Away (circa December 2017):
Royal Blood - Figure It Out (circa May 2018):
Anyone see the underlying theme?
