Hey, yes I remember Paragon Radio! My wife and I used to listen to it while playing CoH back in the day, though we were just passive listeners, never part of the community or anything like that. I recall a lot of crazy fun music: 'unique' Eminem covers, lots of Tenacious D, some Euro pop like Toybox (lol, honestly never want to hear "Super-Duper Man" again ;D), and community created songs (I vaguely remember a Vahzilok song where he wanted to give out cookies?).
Thanks for the trip down memory lane! Fun times!
