Quiana, The reason her and Mariah are beefing is because X-Tina made a comment about her using auto tune in her music! Remember the shirt she had on "Auto-tune is for pussies"! The irony off it all is that Mariah is a freaking power house singer , but she has allowed her vocals to be lazy! She won't have that oomph she once had, but I can see the point X-Tina was making, if you are a real singer you don't need a vocoder to do the work for you, and we all know that Mariah can sing her ass off, but in today's music age, you have to have a look minus the talent!!
