i think that you guys are a bit misguided by the fact that it's a more clean note compared to what he usually does in the bridge of Given Up. listen to the studio version, i don't hear much difference:
When I posted in the controversial notes thread, someone (I don't remember who) told me that it was a D, and actually i hear a D too now, I want more opinions, because if I'm not 100% sure the note won't be added.
Added the B♭4s from Battle Symphony, i was expecting lows even in that one but unfortunatly only bottoms at F3s. Anyway he really took singing lesson for sure, there's a real improvement, unfortunatly the change of the band' s style is... meh.
