I find the persona of the song's narrator REALLY unpleasant - stereotypical misogynistic arrogance putting down someone else's pain (presumably the addressee is a woman) with that "you think you've got it bad? let me tell you something..." crap. And there's nothing in the song that suggests McTell was being in any way ironic.

And the tune is trite and whiny.

Whatever genre you assign it to, it's shite.
