This retro confessional has been around for a while - Monroe started the tune when she was 17 and was helped by singer-songwriter Lori McKenna
and frequent Taylor Smith collaborator Liz Rose. The song finds Monroe addressing more than just a hangover, though. "Obviously, the first thing you think about a "Morning After" is when you've drank too much, and most of us have been through," she told Billboard
magazine. "But, it could also be about heartbreak in general. Anytime you go through one, and you wake up the morning after, it hurts. I think you just keep going through the morning after, as it never stops coming."
