Description
When using Apple Music (IPhone5, iOS 8.4) with my car radio (Volkswagen MIB II), I can browse through a list of all albums, playlists, artists and songs on my radio. I am currently not able to get this information on my radio when using Spotify. This causes the need to grab my phone everytime I want to change the album or playlist.

A more detailed description, using numbered steps
1. Start play a playlist using USB or Blutooth on my iphone 5 (ios 8.4)
2. On my car radio, press the "browse content" button.
3. When using Apple Music, I can choose Playlists, Albums, Authors, Tracks, etc
4. When using Spotify I get the message that there is no content available.

What I expected to happen
I am able to browse through the albums, playlists, authors, etc using my car's infotainment system when streaming spotify content.

What actually happened
My infotainment tells me, there is nothing to show.
