Safe app for music?

Our family was using Apple Music. The explicit filter fails all the time and I finally removed it from my kids’ phones because I discovered that music videos aren’t rated, so they had access to all types of uncensored videos. Any suggestions on a way to play music on a smartphone (iPhone) without having access to everything in the store?
