FAMOUS SINGERS BELTING/MIXING B5 HIGH NOTE! 

Pointing some things out:
- Tori's is slightly flat but still B5
- Gwen's started off flat but it ended centered
- Perrie was supposed to hit an A5 but went super sharp and hit a B5.
I may or may not have made this video selfishly solely because Demi hit new B5s recently 😭, also, i wanted to innovate a little, so i used old AND new/less used clips.
