I get what you mean when you said it reminds you of BTINH. When I first I heard Jealous it seemed like she was singing and leaving the beat but after a few more listens it clicked and it became my fav song.
Why does no one Like BTINH? I will be honest at first I didn't like that song at all...still don't like it but I love the chorus.
BTINH and Jealous sounds like two tracks bey recorded in hopes of getting a Irreplaceable type of hit. They don't sound original in comparison to the rest of her fresh and organic discography.
