I just don’t know what better option exists to retheme this. You can’t really keep it Aerosmith forever because they only get less relevant with each passing day (do teens still listen to Love in an Elevator?)
There aren’t really any new major rock groups with a catalog well-known enough to anchor a ride. Nor is there a great fictional equivalent (no, Powerline is not better).
I think the best way to go is a randomized playlist of rock hits from all eras, which seems to basically be what we are getting only with a Muppet twist. I can’t be mad at this

.
Could have been much worse, just look at Paris.
