Whatever makes you feel better

I doubt there is one specific.

Anyway Madonna, Lady Gaga, Beyonce, Taylor Swift, Adele

Adele is very powerful commercially, but I doubt she has the network that Gaga, Bey and Madonna have, but maybe she'll get there ( I doubt it tho, she seems more closed to opening new doors for her than the other 3)

Powerful ... ? Are you taking it literally or what ? No one is talking about vocals here

delete this

this list makes me cringe everytime i see it.

Most of the people understand Christina to be able to deliver a strong vocal.. but at what costs? She's straining, screaming instead of singing and mostly off key. But whatever works for the author of that RS article

Adele
