I dont listen to alot of Ariana Grande so I'm not the best person to ask about this, but I'll try to be as objective as possible.
overall, I think its a solid track. everything comes together without any problems, the chord progression is laid back and the melody on top plays off it naturally.Their synergy suggests a vocal melody to the listener pretty strongly, so I could see AG's writers or even AG herself easily coming up with the appropriate chorus to go over this, and in my head it sounds pretty close to what you'd hear on the radio.
nicely executed. I can't offer any meaningful constructive criticism here since like i said it's not my cup of tea, but from a commercial standpoint I don't see any reason to dislike it.
