"Stars Dance" & "Only Human" aren't bad ones. I really do love "Stars Dance"; it's sounds so magical and somehow romantic.
"Britney Jean" isn't a bad album title but since we had gotten "Britney" before, it's incredibly lacklustre. If she had been trying to find a self-reference album title again, just "Jean" would have been enough.
I usually hate album titles with self-references, especially by bands, e.g.
Jedward - Planet Jedward
Spice Girls - Spice World
Backstreet Boys - Backstreet Boys
Backstreet Boys - Backstreet's Back (the follow-up album of "Backstreet Boys"
Others I really dislike:
Ashlee Simpson - I Am Me
Beyoncé - I Am ... Sasha Fierce
Flo-Rida - R.O.O.T.S. (Route of Overcoming the Struggle)
Lady GaGa - Artpop
