RIDICULOUS!!!! HI definition radio. Sounds just like the last ditch effort it is to even attempt to save terrestrial radio from DYING like IT SHOULD. CLEAR CHANNEL has been the sorriest monopolizing Piece-O-Crapola media group to EVER touch the airwaves. If you buy into this HD radio bullshit, enjoy your HI DEF commercials, and TEN IN A ROW at that!!! And then, for your listening pleasure, HAND PICKED CLEAR CHANNEL Content Advisors that let you listen to the SAME "currently mass popular" CRAP SONGS OVER AND OVER AND OVER AND OVER AND OVER until you are completely sick of them. I'm sorry, but HD radio is a freakin JOKE and anyone who doesnt see this as a DITCH EFFORT to have some market standing against satellite radio is without hope. Ever since they ClearChannel started buying all the radio channels in TX it has gone DOWN THE TUBES BIG TIME.
