Gaga's album titles are perfect the way they are... The Fame is perfect, The Fame Monster, not exactly but Monster alone is perfect and since it's an EP/Re release it makes sense. Born This Way is perfect, ARTPOP too.
BEYONCE - Blue or No Angel would be cool.
1989 - Clean
PRISM - Dark Horse/Ghost if the album was dark. but PRISM is also kind of good considering the album is not dark.
Unapologetic is good, could've also been Paradise tho.
R8 should be called "No Time" goes perfect with rih's IDGAF attitude + 45S
TTT and Loud are perfect album titles, Teenage Dream too.
Adele's 21 also.
Beyonce's 4 as well.

And they all fit too
