Pop music wouldn't work since their target audience is females 18-25, while the class of pop is more reserved for tweens and teens, but they are considered a Pop CHR by Arbitron. As for WQHT being a Hit music station, they are a hit music station, but because they are classified as a Rhythmic CHR (similar to WHYI-FM Miami Y100), they want to flaunt their hip-hop and R&B style. Plus, their target audience responds better to the slogan "hip-hop and r&b". Z100 kind of changed the meaning of hit music since their inception, people think hit music is pop. A marketing genius.
