Unfortunately, the comedy channels do not have a lot of base content to go off of. There's only so many comedians out there that produce content, and an even smaller fraction that are willing to license their content to be aired by Sirius. So, you get a lot of repetition. The music-only channels and of course talk radio have a pretty good selection of content to listen to. You do hear the same songs if you listen several hours a day because they play what's currently popular, but it's the same way with terrestrial radio, and Sirius has a larger library of content to go off of.
