I know it's far too easy to pick on the auto-tune, and I know this is more comical than straight-up bad, but still. I was made to listen to three different versions of this song tonight and the weird wavery chorus part is ear-bleedingly awful. Plus the whole idea behind the thing is ridiculous - it's not "it's my birthday so you should have sex with me," it's "aren't you lucky to be able to do it with me on your birthday?" He even says he's not going to get her a cake! AWFUL.
