not like shes been hiding it. she doesnt need to do that on every single song. plus shes POP. comparing her to aretha doesnt make sense. shes making pop songs. with big hooks. shes not about bringing the house down with emotive/powerful vocals, not on every single anyway. she needs to create a big pop hit. big singing isnt necess the best way to do that. anyway, shes allowed to try out diff vocal styles from time to time. thats what makes good singers.
