Rizzuto was #1 in STL when KPNT was pulling 2.5-3 shares. Yes he’s definitely a huge force to be reckoned with and has pulled in an even larger audience than he used to have, but the rest of the station has caught up.Once again, KPNT wouldn't get those good numbers without Rizzuto in the Morning. The music isn't the attraction. It's Rizzuto.
Also, as far as "the wrong currents," that wouldn't happen if you had record label promotion staffs prioritizing the songs so radio would have more information in picking songs. Otherwise it's all based on personal taste, which is not how it's supposed to work. Since the record labels no longer promote rock or alt to radio, those stations have little guidance or information about what to play. That doesn't happen in other formats.
The radio add board says otherwise with the promotion. Arista is pushing a new Maneskin song very hard. Concord has ads for Ghost’s “Mary On A Cross” on AllAccess. Fueled By Ramen is pushing a new All Time Low song hard too. Atlantic is pushing a 2nd Matt Maeson single from his new record hard to Alt as well. Epitaph has managed to get Falling In Reverse to gradually crawl up the Alt chart with a lot of hard work to get many stations to try out a heavy band. Labels definitely still try.
