I like the fact that some songs are just meant to be funny (I'm Going Bananas, Cry Baby, ...) but with other ones I think they should have been left out of the entire album release because it was just not up there with the rest of the quality on the album.
My worst 5:
Hey You: never would've guessed this was by Pharrell - in between the singles 'Jump' and '4 Minutes' this simply was so forgettable !
Revolver: Madonna featuring on her own record. Not a Madonna track in my opinion.
Bitch I''m Madonna: maybe funny, loved by many, still don't get it.
Superstar: not even good enough for B-side material...
B'Day Song: Shamefull...no really...shamefull....
And thank God never included on any release:
Angels With Dirty Faces: clever it was left out but glad I heard it.
I Can't Forget: extremely boring
Arioso: zzzzzzzz
Score: good I heard it, even better it was turned down
