I recently learned about buying Mp3s on Amazon. Most CD purchase pages have a "purchase options" and you can do Mp3s. I do that for mainstream things for my kids that aren't on bandcamp (such as music from a kids TV show).
I'm actually working on a IoT device where one of the main goals was selfhosting audio content for my kids. Uses AI for the user interface. Similar to Alexa but battery powered. Still in private beta (orders are closed right now) but here is the link for anyone curious. https://heycurio.com/
Ah. AG Talking Bear meets LLM. I started working on something similar a year back - but tried to keep it restricted to offline which made it more challenging since inference on CPU of raspberry PI limits you to very small models.
Sending voice clips of children to an always listening server is just a bit too dystopian for me.
