Ok. I was getting confused by the delay and the initial lack of control. I couldn't tell the difference between a delayed change and an automatic change. Thanks.... point still stands that it's simply a bunch of fake tv clips, probably all the exact length of the song.
No doubt. It seems each "channel" is a complete music video in and of itself, and the channel buttons switch between synchronized streams. And, like my TV, it feels like it takes too long to switch channels. ;)
