which functions are suported by Spotify in connection with Android Open Accessory Protocol Version 2? I know that the basic functions (play, stop, forward(back) are supported. But what about choosing playlists or interprets from your sportify offline libary.
Background: I'm searching an alternative for my ipod classic in my car. My thought is to put an old smartphone with a sd card and spotify in offline mode in the glovebox. So I have my music with me and there is no need to stream all the time. But when I have to change playlists or albums on the phone, this is no solution.
