Book Radio was dropped last week to make room for Rural Radio. Supposedly all or most of the Clear Channel channels will be dropped from the XM side sometime next month. The corporation is being hush-hush about it, but the CC voicetrackers on the affected channels are urging listeners to besiege XM with phone calls, emails, etc., protesting the channels' impending removal. They're also plugging iHeartRadio. Nice to have a content "partner" trying to turn your listeners against you, huh?
