A case of the Fiery Furnaces - You can't stick to one goddamn melody, and your songs approach infinity in length.
Barenaked Ladies Syndrome - Nobody outside Canada cares about anything except "One Week." Nobody inside Canada cares about anything except "One Week" and "If I Had A Million Dollars." Your fans cry about it at night, but only to themselves. What?
Franz Ferdinandery - You had a fantastic genre-crossing hit... but nobody cares about the rest of your album despite it being one of the best albums of the year, and then you show up in a PSP commercial, making your non-PSP-loving fans die a little inside. You should be Nintendo people, dammit. What?
