It's technically copyrighted. Everything on that CD, music lyrics, song titles, photos and band name, is copyrighted material. On top of that, Wintermask was a different band with different members, just like BloodHaze (the other three members' previous band) was a different band with different members. It wouldn't feel right to go uing the titles of bands that we are no longer a part of.

And before anybody starts up with the obvious suggestions of "WinterHaze" or "BloodMask", I've already considered that and it's fucking stupid.
