Filter for explicit songs from the music library / services

Spotify exposes the APIs for Sonos to create the App.  I would be very surprised if the APIs did not provide access to explicit content information....and if they didn't, I would again think that it would be a bit of a no brainer for Spotify to be able to add that information.  My guess would be that Sonos doesn't want to invest the time/money into adding the filtering functionality within their app.
Thanks for clarification.  It's interesting though that if you look at some of these Music Service Apps (Spotify, Rhapsody and Napster - before joining Rhapsody), they're identical in terms of functionality and look and feel.  Which tells me that Sonos is limiting what these services can provide.

Not really.  Google Play Music certainly has many more functions than either Spotify or Rhapsody, including Cloud based music and extensive radio features.  MOG had radio services for artist and like-artists, Pre-Rhapsody Napster had automatic playlist generation, which is very unique.  So I'm not sure we can pin the lack of Spotify services like Spotify Radio on a limited API. 

That's great that individual services have their own filter.

My question is how do I partition out explicit songs that are part of my Sonos library?  If I want to be able to listen to mature songs when the kids are not around, then those same songs are always available to my kids, and I don't want that.  There needs to be a way to partition portions of the library that are mature or to password protect explicit songs.

Is anybody at Sonos listening?

I have found Songza has many radio edit options under their "Children genre" . This is working for now. 
love our sonos. Could not go without!!!

I have found that Songza has many radio edit/ clean lyric / kid friendly options under their "Children genre". That has solved our problem for now. 
I love our sonos system. I don't think I could  give it up. I know my children are hooked. 
Thanks! 

Hello, Sonos does not currently have a way to filter out explicit songs or activate parental controls. However, if this is something you'd like to see from Sonos in the future, I can change this topic to an Idea thread so others can comment and +1 a request for such a feature.
Really need this, I don't want to go to Napster or Spotify to enable/disable this type of filter when the kids aren't using the Sonos... the filter function is a personal choice so naysayers on censorship can ignore it.

I would REALLY like to see this feature added to Sonos. The ability to filter explicit content is needed.

So Ryan E, what is Sonos's definitive plan on this topic? Is filtering out explicit content on the product roadmap or not? If yes, what are the timelines? 
If product management is basing their decisions solely on how many "Likes" there are on a particular "idea thread" (this one has 22 as of the time of this post) I would say that this is not representative of the whole Sonos customer population. How many customers want this feature (filtering out explicit content) but have no idea about the "idea thread" process? You could be in a situation where 85% of your customers want this but only 22 people searched long enough and were so inclined as to write a post here. Bottom line is that customers want to control content in their homes and the right thing to do is to provide that control.
I'm looking forward to hearing the definitive plan.
Thank you.

+1. My own library is my problem, but I need the ability to block from all Music Services, particularly the 'Flow' on Deezer.

Adding the ability to block explicit lyrics would make Sonos perfect.
