Rehab is one of the worst, possibly the worst, songs I have ever heard. It is almost all in the same tone and pitch. It has a stupid basis, "I'm going to rehab, oh no I don't have time to do that. And my dad says I'm fine, so obviously he knows everything." If she wins any awards, especially for this song I am going to be very disappointed in whoever gives it to her. She is also very masculine and tattoos, what the hell? I hate this woman.
