I definitely do hear when her voice is tired. It tends to have more rasp and a little bit of strain at times. The funny thing is that she still sounds great even when her voice is tired & still better than so many in the business today.
if u want a “part 2”, watch (and react too!!!!) the fail Vs. nail one. it’s kinda similar, in some fail clips she ain’t tired but if you liked this one u will definitely like the fail Vs. nail compilation
