I dunno, they seem to have a chip on their shoulder with catchy melodic stuff ever since they were accused of selling out with More Than Words, that became a real albatross around their neck. It's the Styx with Babe, Scorpions with Winds of Change, Mr Big with To Be With You or Manic Street Preachers with Everlasting syndrome.
None of those songs were bad or overly contrived, yet they all suffered the fate of being overplayed and pigeonholing the respective act forever. But people like ballads, that is just a fact of life.
I've never had issues with ballads/'girlie songs' or overtly melodic stuff. I can listen to Black Sabbath and then switch to Beach Boys or Bee Gees, no problem. I have really hidden, deep and dark guilty pleasures!
