FreeTube looks really interesting (i had to scroll past a lot of sex sites to find it though 😉 here’s the url for others https://freetubeapp.io/). As for Spotify, I know someone who downloads playlists as a DJ. He uses a piece of software to do that, but I don’t know the name if it. It is illegal though. So far I’m still in control of listening to music, but we have Sonos speakers in our home. Daughter has one of her own since recently. I create playlists for her she can turn on and off in her room. Most of the time she just ask for what she wants to listen to and I start the music for her.
