If it were a differential issue you would hear it turning and this issue (which is the same as the videos above) can be heard when in a straight line sometimes when applying throttle, sometimes not. That says it's something else and I'm convinced after hearing it with the windows open at low speed that it is a heat shield/suspension related issue.
A heat shield would better explain what I heard the second time. Though in my instance it sounded like it flew off the car
