I know what you mean. I can't listen to Mark Olson, formerly of the Jayhawks, for the same reason.
They came throw our Satellite radio station last week. I stopped right in the middle of what I was doing...walked over to the unit and turned it off until their pitiful song was over. I heard like one or verses about "kissing @ss" and knew right away it was them. They sounded like high school kids.
