I actually listened to Gaga's discography a few days ago and this is what I have to say:
The Fame: Utter ****, I was shocked because the singles were flawless but the rest of the album is just awful.
Starstruck....

a 4/10 (a 4 only because of the singles, it would get a 0 otherwise).
The Fame Monster: Good, a 7.5
Born This Way: Definitely her most interesting and ambitious albums although a little inconsistent , I'm surprised the Monsters hated it(At least that's the impression I get). 8/10
ARTPOP: Surprisingly good

It feels laid back and fun, not as pretentious as the titles suggests. My only problem with it is that the second half gets a little repetitive and it was longer than it should have. 7/10
