Y'all are doing to much on this.Sure,it's not as good as it should be but put it in the context of the book and film...
*If you haven't read the book there will be spoilers ahead but seriously it's in the early parts so it's not a big deal*
André is Tom Buchanan,cheating on his wife without a care in the world.B is his wife Daisy,whose interest is in Gatsby (Well,it's really in herself because she's so vain,vapid and self involved....)
Once that guitar comes in around the 1:20 mark the track really takes off. Beyoncé sounds amazing, I can't wait to see how this is used in the movie. I'm going to need to hear an untagged version to fully judge André 3000's part, but so far that's the biggest head scratcher of any bit of music I've heard from the Gatsby OST. I wish they would have let Bey do all of Amy's vocals, and had 3 Stacks add his own rap verse.
