No, I didn't find a listen link either. Looking at the playlist, I would say that every one of us has those tunes all on three to five CDs anyway.
Still, like you say, it would be fun to listen just to see how they are being "Christmasy" in August. Either the staff has to hate it or are having a blast with the theme.
Did you see the Dee Jay names? Looks like screen names for a Christmas forum to me!
Too bad kgstyles is deployed. He could record us a soundcheck of KMOX. Hummm, I may contact the station...
