The reigning queen of country-pop is on this list for her highly publicized love life and overplayed generic (although catchy) songs. She’s become infamous for writing snarky songs about her ex-boyfriends. Her list of famous exes includes Jake Gyllenhaal, John Mayer, Taylor Lautner, Lucas Till, Joe Jonas, Conor Kennedy and Harry Styles. But it’s hard to sort out the genuine from the obvious publicity stunt pairings à la Henry Cavill and Kaley Cuoco. If her music wasn't a carbon copy of early 2000s Avril Lavigne, we'd probably take her more seriously.
