Yeah for V's blue and grey song he had the background music ready and everything seems set and prepared even the lyrics for placing it in his mixtape. (I actually like this version much better than what they did to it they even changed the lyrics V already put.)
Maybe he said something in it that was going to be a hint for something. However, they liked the concept of it so they just altered it.
However they kept the beginning guitar solo and kept the first 3 words of wheres my angel.
however, I suppose this is just another piece of evidence that they hurried to change everything. V might release his album later on in the year so they just decided to take one of his songs change it up a little and making it into a song to put into their main album.
This makes me salty haha.
