Telephone. That thing was absolute shit. And I swear I own at least two songs she ripped off in it. However, that's as far as my hatred goes.
Oh, and when I said I didn't care, I mean I'm not going to go around listening to every single thing she's ever made. It means I'm going to completely ignore her, or, as that's not possible, not form/express opinions. For example, Bad Romance wasn't that bad. I mean, I could do a better version of it, but thst's just 'cuz I'm great, and in no way has any bearing on her talent.
For the record, I usually only listen to singles whenever I look up an artist initially, so when I say "Majority", I usually mean the majority of the artist's singles.
