The following is the lame answer I got back from KKGO here in Southern California:
Go Country 105 is a mainstream country station that focuses on charted
songs that are big in the market. While there are country stars lending
their talents to appear on the John Fogerty project, none have charted in
the range on the lists we watch. If that should change we would certainly
take a look at how that may play into our playlist.

My comment is,how does a song chart if its not played???
