I think "Classic " formats are pigeonholed. Classic Rock purists believe the format has a certain sound for a certain audience. None of the music can be mainstream. Classic Hits can only have a certain sound which generally is rock based mainstream hits. Classic Hip Hop is pretty much 90s and 2000s based "crossover " or Top 25 Hip hop songs that were crossover hits. None of them radio stations are willing to expand these formats for fear of losing their core audiences. The only problem is that if they don't expand their Playlist, their audiences will disappear altogether as their core audiences age. As I stated before no one i know under the age of 40 even listens to radio. Between the repetitive and the commercials why would they?
