It depends. This is a low pressure time for a station to change formats. They will have a few more months to fool around with the music before it matters. By April, they will have to deliver ratings and demos. We'll see how this music mix works in terms of delivering ratings. In Philadelphia, where the CEO of Entercom lives, there is an alternative station there that gets great ratings. He' s probably listened to that station even though it's owned by iHeart. The biggest complaint listeners have with the station is the playlist size. It's not a huge playlist. But it gets great ratings. The ratings often drop in December, but then recovers in the spring.
The thing about those worn out 90s songs is they attract ratings. They did it at WRXP, and if this station needs ratings, you might see them try again here.
