Spotify is our preferred and Apple Music is a close second.
The user interface on both is extremely easy to use for all ages and they both provide a family/multi-account plan that will power all three transmitters. *
*(You still need three devices and three accounts, but the family plan gives you multiple accounts that can be played on multiple devices simultaneously.)
Our clients also have good succes with YouTube and Amazon Music and SoundCloud and literally any streaming audio/video platform out there.
