I'm sure there are a lot more that I'm forgetting at the moment, but I've always absolutely despised "The Climb" by Miley Cyrus. I can't even explain WHY I hate that song in particular, but it drives me insane.

Others that come to mind are "Love Song" by Sara Bariellies (or however you spell it), and pretty much anything by Colbie Caliet, in my opinion.
