I don't understand how some of these artists sell out concerts. They must lip-synch, because on the rare occasions when you hear them live, they're awful. They can't hold a note to save their lives. Miley Cyrus is a prime example. I heard her do "The Climb" live and my dog is STILL howling from the sharp notes she hit. Taylor Swift is another one. She did a live duet with Stevie Nicks at the Grammy Awards and she was frightful. Stevie Nicks' voice has been on the decline for years now, and she still sang rings around Taylor.
