they pulled it for now, they were just testing as far as I can tell It showed up a few days ago on my line up and my premiere gave me a message box that this channel had been added. Then it went away. I guess it could be possible tribune media jumped the gun and added it to the line up for tivo to early as well, but it's odd only one was added. I think more likely is it was mapped in the cable card stream.
it will be back, we are supposed to get all music choice channels soon
