I know that verbs must always be the second idea 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 the second idea.

I have also seen examples like this elsewhere

  Can someone please clarify on why this is so?
