Can't sync local files + Last Update destroyed Lockscreen control etc.

[Mysterio]

Hi, 

I have synchronized a lot of good, local stored music via Spotify playlists on my Samsung Galaxy S3 from my old PC (which is broken now and consequently all my locally stored music is gone) .

Now I have a new PC and want to sync my "locally stored" music back. From my Android to the PC!
How does it work? I see my Android in Spotify on my desktop, but it does not synchronize the music back to my PC.

Another problem. Since the last update (before yesterday) I can no longer control Spotify from the lockscreen! 

Moreover, the current song is no longer automatically paused when the headphones are pulled out!!! The song is then played out on the loud speakers - which is very annoying, disturbing and embarrassing!!!!

I can not make [Android] Troubleshooting Spotify [ New ] because I would lose all my "locally stored" Music on my phone!

PLEASE help me!
