Shallow playlist, repeating songs and/or artist too often, not keeping the playlist fresh. Failing to add music and take away music on a daily basis to keep the playlist unpredictable. I can tell you right now on Sirius there are channels that I can almost set my watch to in terms of the stale playlist and they play the same crap over and over with very few adds and removes to keep the channel fresh.
XM'ers are use to having deeper fresher playlist. Sirius is clearly going to have the change their overall philosophy or this isn't going to happen. This also doesn't mean that they have to necessarily move away from their hits based style, but they do have to dig deeper and keep it fresh.
There will be some channels were repetition is expected because it is hits based and currently tunes. But overall not all channels should be like this.
An example of a channel with terribly stale playlist is Roadhouse. My GOD it is barely even mixed up day by day, but you hear the same set of songs almost over each day. Now American on XM, always seem to mix it up, keep it fresh and interesting. You never knew what they were going to play. So that is why I say Sirius isn't going to be able to continue with shallow playlist. I think if they do this, then they will see folks churning away from the service.
By the way you can have some channels with shallower playlist than others, but you still need a good core of channels that have good healthy playlist.
