What are you talking about? Is she lip-synching when? I have no clue what you're asking...
In concerts? No
On her album? No. But they do alter her voice to make it sound better...
Taylor has to lip sync on her videos, she cant sing live and shoot at the same time. but then her songs are real and her voice is real and it of course rocks. If u see her interviews u'll understand that her the voice she speaks in and the voice in her songs is the same. in concerts also she duznt lip sync, then what is the use of a concert?
In the music videos, it is lip singing because she is moving around too much and it would mess up her singing. In concerts and albums though, she's singing for real.
