There are a lot of sunbelt and west coast cities that are “younger” yet support formats such as mainstream AC and classic hits. The difference with Atlanta is there is such a large urban component that the amount of signals that could program either format are limited. You could say the same with Spanish in some of these markers but I most don’t have 7 FM signals (not counting translators) dedicated to the format, plus they have more full market FM’s (another issue with Atlanta).
