But I've never heard "one song per series" being a rule until just now. Even if it was, it has no bearing on the relation to the potential characters.I mean that's 3 blows it's taken.
How many times we gonna readjust it?
It doesn't matter how many "blows" something takes, if it keeps getting back up then it doesn't mean anything. Nothing has completely KO'd it.
Again, trust me, I REALLY want music theory dead. But nothing has indicated that it is.
