Artpop is my fave, it is very colorful and fits the album so well.
The second one is the standard (amazing) cover of TFM, it is just perfect.
The Fame is third it is iconic and one of her trademark pics I think.
TFM deluxe is the fourth, it has that iconic hair I adore.
BTW standard is the fifth one, I think it is very good and innovative minus the fonts.
And the worst is the BTW deluxe: I hate the closeup of the face plus her hair is not my fave that way.
She has great album covers
