I built this for my niece when she was very young. A raspberry pi and a little amp and some speakers with a usb nfc reader. Wrote NFC stickers and stuck them to little cardstock 'album covers' that I laser printed. When she put the card in the little box with the nfc reader it would trigger a python script to load the proper playlist into vlc and play the album. If you took the cover out of the box it would stop and clear the playlist.
