Speculation: Radio Disney is still a pop music network (in the informal sense), but most remaining listeners are streaming it because the AM stations have been largely abandoned or sound like crap. Having KRDC continue to be the OTA "flagship" guarantees that Disney continues to qualify for broadcast-tier publisher royalty costs and no performance royalties, compared to all-streaming services such as Spotify. The Soundscan savings might justify the ongoing operating costs of the station, which would be low overhead, no incremental headcount, and basically a sunk cost (except for electricity and minimal technical maintenance).
