Mess @ you guys not knowing how Watchmojo does it's most hated list.
There's a disclaimer saying something like "We're not particularly saying we hate these songs, but we could see why they would get hate."
Anyway, lists such as these, unless they asked every single person on the planet what songs they hate most, can not be objectively true. Whether or not you agree with is up to you.
(OH, and before I'm called a Nicki hater or something: Timber was #10 and Kesha is my fave.)
