Probably should have posted this waaaaay earlier but better late than never.
Me and a few friends of mine have been working on gathering FC proofs for every C3 release on guitar. Over the course of almost 3 years, we have whittled down the list of unFC'ed C3 songs on guitar down to 7 (not including 2x, rhythm, karaoke, or radio edits).
Spreadsheet of 2013 Releases Documentation (3 Songs Remaining)
Spreadsheet of 2014 Releases Documentation [1/2] (1 Songs Remaining)
Spreadsheet of 2014 Releases Documentation [2/2] (2 Songs Remaining)
Spreadsheet of 2015 Releases Documentation [1/2] (COMPLETE!)
Spreadsheet of 2015 Releases Documentation [2/2] (1 Song Remaining)
Here are the remaining 7 songs left to be FC'ed:
Chemical Warfare by Slayer
The Devil Went Down to Georgia by Steve Ouimette
Fury of the Storm by DragonForce
Her Ghost in the Fog by Cradle of Filth
Lie by Dream Theater
Schizophrenic Seizure (ft. Paolo Viteri) by Superfluous Motor
Somewhere Back in Time by Ascension
