That album will never be named "7".
It is just to keep the new album name a secret.
She would never ever choose a name for an album without a deeper meaning behind it..
At least I hope so.
Do tell me what the deeper meaning of LOUD, Talk That Talk or Music of the Sun is? Also the album will not be called Rihanna7 it would be "7" by Rihanna. Its not like Isis would have a deeper meaning y'all just like it cuz its an egyptian goddess.
and ROL was Madonna's 7th album.
