It is all speculation and way too early to guess. You can't assume what decisions will be made because the business model has changed.

There is also a good chance that XM would have dropped their folk channel, but the addition of Bob Dylan's show gained attention to the channel.

IF the decision is made, it will not be because one person doesn't like folk music. It is because folk music is not drawing enough people to satellite radio.    I notice there are no channel dedicated to polka music. If someone could come up with data that would show 100,000 people would sign up to listen to polka, and only 1000 are listening to folk - guess which station would stay.

It comes down to supply and demand. Satellite radio is not a public service, it is a business.
