Description

I rebooted my phone while putting gas in my car this morning. I had been listening to an offline playlist via bluetooth when I shut off my car. When the phone turned back on, all of my synchronized files (with the exception of local files I synced from my MacBook) were gone. The phone is now redownloading all of the tracks. I am unable to replicate the issue (I haven't been able to cause it to happen again; it only happened once).

A more detailed description, using numbered steps

1. Opened Spotify while still in my house and chose a playlist. Paused it.

2. Got into my car and started the engine. Bluetooth kicked in and started playing my music automatically.

3. Listened while driving for 30 minutes or so. 

4. Turned off the car at a gas station. Bluetooth kicks off. Spotify pauses. 

5. Turned off the phone (holding top button only) to reboot. Didn't close the app first.

6. Booted the phone back up and noticed immediately that all of my offine playlists were now unsynched.

What I expected to happen

I expected to reboot my phone and find all of my tracks synched as usual.

What actually happened

I rebooted my phone and all offline files were gone. I verified by checking Spotify's file size on my phone. It went from ~8 gb to 2.

Did offline syncing work fine before you updated to 0.7.1?

Offline synching has worked okay for a very long time. Most recently, I deleted the entire Spotify app from my phone just to clean up the database it stores (it had grown unusually large). This is the first time I have rebooted my phone since reinstalling. I have noticed in the few weeks since I resintalled the app that the app has been redownloading offline tracks more often than usual. A few tracks here, a few tracks there, sometimes an entire playlist. I just assumed the tracks had been updated or changed somehow.
