She has a good voice but NO stage presence. Look, she can sing great but shes singing like shes in the studio. Its too calculated and shes trying to hard. She doesnt look like shes having fun. Sometimes its better to sacrifice certain notes so you can move around the stage and interact with people more and be loose. I think shes being hyped because she has a good voice and can sing live. She should have done the normal version and saved the acoustic for radio station visits or talk shows. Plus, I cant take the song seriously as an acoustic song. Shes singing it like its a deep meaningful ballad when its really a trashy dance song. Could you imagine Ke$ha doing Tik Tok (if she could sing) as a ballad on the guitar? Just...NO. Jessie is talented but shes doing it all wrong. Terrible song to debut with and perform in this style.
