The only thing that's been missing from UNA was erotic Rih, i really hope she's back on ANTI
At least one or two songs
I'm pretty sure that's why she didn't release Jump (the only sex song) as a single during Una, it was the obvious choice for everyone but she didn't want it.
After Loud/TTT back to back, she started to become a gimmick, the sex singer and she knew it.
That's mainly why she went with Diamonds/Stay. A bold move nonetheless.
