No, this isn’t a new track.  It comes from the post-Unapologetic/lead up to X era when the couple briefly reconciled in 2013 and likely comes from the same batch as Counterfeit.  The track show that the two have an undeniable musical chemistry even if that doesn’t apply outside of the studio.  Both of their vocals are strong here with a lack of autotune very noticeable (in a good way).  The song has the two serenading each other about what they plan to do once they get together.  The lyrics and production are solid and give the track that kind of sustainability that could have made it a hit.  We understand why it was dropped from X, but we are grateful to whoever leaked it.
