It's almost Christmas, which means you're probably hearing a lot of Josh Groban holiday music on the radio these days. But Josh admits that if he happens to hear himself on the radio singing one of his Christmas songs -- or any other song, for that matter -- he's the first to change the station. 'I can't listen to myself, I can't watch myself,' he laughs. 'I don't think that's uncommon with performers. I am fully in when I'm acting, when I'm singing: I am in it. I am so in it, people are like, 'Man, that guy's emotional!' ' 'But when I listen back, it doesn't matter if it's a Christmas song or another song, I just, I always turn the channel.'
