Streaming music services + explicit lyrics

[Spoiler]

I signed up to Apple Music for the family sharing to give my kids (primary school age) access to Bieber-on-demand.

Turned on parental controls / explicit content restrictions on the ipad - worked great. No explicit lyrics content playable.

Then upgraded the small speaker they plugged into the ipad to a Sonos. All going well - better sound quality.

Then, I find that using Apple Music through the ipad Sonos app - the explicit content filters don't work. Seems that Sonos/Apple Music can't work together to keep the filtering on.

And searching around, it seems that no other streaming service, via Sonos, will filter content.

Any ideas on a setup for streaming music (like the simplicity), with a reasonable sound system, that will filter content ?

Google and Pandora both have content filters that are compatible with Sonos

If you are already in the Apple ecosystem AirPlay is a good alternative to Sonos. Either speakers with build-in airPlay or an AirPort Express that can connect to any speaker via standard audio jack.

Thanks - will look into both options.
