Ok, after a few more listens, it's not THAT bad. It definitely takes some time getting used to. My only complaint is that I wish she added some ad-ibs in the chorus after the "I'm in Crazy Stupid Love" right when those funky horns start playing. Even a whisper in the background "Crazy.. Stupid... Love" would make it sound much easier to the ears.
If the kept the outro ad-libs "La la-la-la Love, Oh I'm in Crazy Stupid Love" in the first two choruses, the song would be better and immediately catchier. (Though it might be more annoying that way so idk)
Hears to hoping the performance is grand

I can't picture it at all so I'm excited
