You should, while your fave has been on a fast decline and not even a superbowl announcement or an interview claiming she was suicidal made her relevant apart from her generic singles (not even that can save her lately), Rihanna makes headlines just by showing up at events and plenty of major outlets wrote about how they miss her and how Pop music is dull without her, people are just waiting now
Yes, that's probably the case. "Only if for a night" was the rumored title of the Rihanna song too. We even have a snippet (you can barely make out anything though).
All of Rihanna's samples are amazing. SOS, Don't stop the music, Drunk on love, and Cheers. They're all very well fit in the song and add something to the song. She isn't Beyoncé, she knows what she's doing.
