We play music for her and her sister via Spotify on Sonos speakers. Also have an iPad but don't use that much for music, they use it for movies and games on long journeys only. I'd like to get her a tablet for Christmas as I think she's old enough to use it sensibly, but would love it to allow her to choose music herself and play it in her bedroom etc. Any tips on the best device to choose for a complete technophobe??
