I named a couple of octaves wrong. Jojo hit c3 not c2, sorry if there are more :-) I couldn't be 100% focused.
I loved it! Please suggest more like this! Let's talk about vocals!
Pink, Xtina, Mariah, Ariana, Jennifer, Camila, Rihanna, Adele, Tori a many more of well known singers who sung for fun :) Awesome!
