They're running a ROQ of the 90s weekend. The core of their format to this day. The new classic rock in a way. Pennywise, Siouxie and the Banshees, Sublime, Korn, etc.
In my view to make a continuous splash they could be dipping into adventurous new music that no other US commercial station is playing and hyping that up to the max on social, because this exact philosophy is what put them on the map in the first place!
In my opinion the daily playlist leaves tons to be desired, but if they're billing top 5 as noted on this board it's curious why they even departed from the earlier pop lean. Seems they could air anything and rake in the revenue, leaning on their heritage?
It makes sense when you look at the bell curve of alternative's popularity which peaked around 1995 that the SoCal stations like 91X and KROQ that started it all in the 80s would today be playing deep cuts by Smashing Pumpkins while the rest of the country's radio stations have moved on for better or worse.
