I may be wrong, I think the AMI is unable to play any DRM protected tracks, this counts for spotify, and people who are now using Apple music. Very frustrating, especially now that Apple has made it so appealing to start using Apple music rather than buying your songs on iTunes (and playing them on the same app might I add). You now can't play those through your car, unless using bluetooth. I guess the advantage of using apple music you have the ability to skip forward and back still.
