Wfmu is a real radio station based in new jersey, so it will be as “clean” as any radio station. Im sure ive heard references to smoking weed, and some songs may be sexual in nature. But all regular FCC rules regarding radio content is followed.

The ip-tv link is a collection of rtmp web streams. There are specific adult channels up there. There’s also like pbs kids channels on there. You’ll have to use your best judgement.

Another thing I forgot to mention, you may want to check out f-droid.org. it is an open source alternative to the google play store. You should be able to find alternatives to music streaming apps that will not have trackers and ads. Each app’s page will detail any potential privacy concerns, such as interfacing with closed source web services, or ads.
