This is the reason we cancelled Spotify and moved to Apple Music.
Not only do they have a bunch of adult content hidden in there, but they also have tons of "video podcasts" available via search that are compilations of TikTok and streamer trash (like the one you linked). So if you are trying to keep young kids away from TikTok, trash-level Minecraft streamers, etc, but assume Spotify is safe because it is just music, your kids will find it and start getting hooked on TikTok via Spotify. It's really terrible and insidious. It feels like the tech industry is conspiring to get small children hooked.
There is a thread several years old on Spotify support where people have been complaining about this and they have done nothing. They are prioritizing engagement via crappy podcasts over delivering a music product that works for a range of customers (families, etc).
BTW, Apple Music has been totally fine as a replacement. I actually like it more. And there is a web app that will move all your old playlists over in minutes, so there's very little hassle in switching.
