Guys, you gotta let this go. Why would Mix change any part of the existing brand? Do you realize that once you flush the format, there is no guarantee that the reincarnation would out-perform that the current KHMX.
I know the Movin/Kiss/X/Insert Slogan96.5 rumblings have come about, but it actually costs CC more money to flip it without a sure return on the investment. True, Mix does not win in many of it's key demos, but it does exist well, and bill well. Remember that KTBZ is down the hall, and is most likely not looking to lose any of it's 18/34-25/54 numbers,male or female.
As far as Sam goes, HoustonRocker2 is right. Sam cost money, but Kidd is uber-money..and not a guaranteed winner or ratings biller in the market vs. his price. If Sam was gettin the boot, we would be reading about it by now.
