Britney is a worse singer. J Lo isn't good, but Britney is far worse. When you sound constantly bad and 'computerized' on a studio recording. That means you suck and she sucks vocally. Everytime I hear a song from Britney it sounds like the voice was digitally altered and still doesn't sound that good. At least JLo has a much better tone and everything she does doesn't sound computerized even if it is. Let's get real here.
I was being kind giving Britney a 3.
