And they always use rock music! rock music's not their favorite song and we all know that.Tsk5
It could be better if they tied it with a classic orchestra or something soothening like "remember me this way" by Jordan Hill.
About crediting photos, they surely don't care who made that and everything. They make those videos not because they like OTMA and Romanovs for their personalities. They just like the story of how they died (and that's what all they do know) and the OTMA's pretty faces. Anyway just my opinion because some of them might read this if they happen to link here.
