The head of Taylor Swift's record label is fired up and ready to defend his superstar from people who are criticizing her Grammy-night performance. "She is the voice of this generation. She speaks directly to (her fans), and they speak directly back to her," said Big Machine Records CEO Scott Borchetta in a phone interview. "This is not `American Idol.' This is not a competition of getting up and seeing who can sing the highest note. This is about a true artist and writer and communicator. It's not about that technically perfect performance."
