It's one of the factors driving generation Z to streaming.
Where they stream the same 10 pop songs over and over. If you compare the playlists of these two stations with the streaming chart, they look very similar.
Comparing playlists, WIOQ has about 100 songs, and WTDY has about 65 songs. The difference is that WIOQ plays the Top 10 songs more frequently (127 vs 116 spins a week). WIOQ also sticks with recurrents longer, and most of those additional songs on their playlist are recurrents. Might explain why their 18-34 numbers aren't so good.
