I think a major signal would have to expand on the Yacht Rock definition to be more of a "soft rock" type of approach, and it would likely have to have a limited number of currents and recurrents to avoid library burn.KAZM is heavy on “Yacht Rock,” but still plays “mellow” ‘70s songs that wouldn’t fit the label.
Our frequent poster Buddy Shula from Buffalo just sold his Yacht Rock FM in Key West... perhaps he can give some additional perspective to this as he actually created his format there.
