Does the biggest vocal range determine the best singer ever of all time?! If so... the prize goes to Axl Rose... 

Here's a rundown. 

Go 'head, Mariah and Xtina up there towards the top!

This is all based only on recorded songs, so some people's ranges may be even bigger [or maybe smaller if they're in love with autotune]... but I found it pretttyyyy fascinating to look at. [Unless it was just the ADD talking...]

If you click the link, you can make it interactive and see more people, and arrange it based on highest/lowest note. I don't see Ariana Grande on there, though.. I really wanna see where she stacks up. 

Also.. props to Prince for having the highest male note.
