Its a song by Rhianna, It seems like the old Rhianna is coming back to certain people. Isn't as poppy on how recently she has been its more of a slow love dovey song.
One person: OMG! Have you heard that new song California King Bed?!
Two person: Yesss it reminds me of back in the days when I would listen to Unfaithful by Rhiannna.
