Never thought I'd see the day Power 96.1 trails Rock 100.5 by nearly a full share. (The latter station benefits from a talented morning show + the recent demise of Alt 105.7. Their numbers would be even better if their PD weren't so clueless.)
CHR/Pop and FM radio in general has an audience retention issue with millennials and Gen Z given the pandemic-induced paradigm shift in work location. I think a lot of folks are realizing they no longer need FM radio for music. A select set of CHR/Pop stations, such as WKQI in Detroit, have very strong LOCAL morning shows that connect well with young adult listeners.
Power 96.1 has long had a rotating door of morning shows, which I've never understood, since some have performed decently in the ratings.
