I've got the smart phone interface and it's good when it works. For some reason it decides Spotify isn't working for days on end. When that happens, and if I'm fussed about listening to Spotify, I've used the Bluetooth connection and you can scroll through songs in an album but the rest has to be done from the phone. Mine seems to pick up from Bluetooth where it left off from on the phone, so I can connect the Bluetooth as media and then it will play the last album on Spotify (or more often the audio from last movie my daughter watched in YouTube)
