Supoerbowl Pre-Game performace

Is it just me or was Michelle Branch lip syncing her and Santana's hit song? It sure seemed like it, performance sounded WAY too much like the recorded version. Beyonce did seem to be singing herself and Michelle seems to be singing now in this piece after her song, but it sure seemed to me like she wasn't really singing (or at least that wasn't what they were braodcasting) for her main song. It makes me lose a little respect for her, as I really think she has talent and to see her lip sync makes me think she may be a bunch more produced than she comes across.
