I know that verbs must always be on the second position in sentences but I had recently found some places where this isn't the case.
For example, in one song I find
Wär’ heut’ mein letzter Tag, ich lebte ihn mit dir.
Surely the lebte would become before the ich, so it can be on the second position.
I have also seen examples like this elsewhere. Can someone please clarify on why this is so?
