My Question or Issue

I have a Offline Playlist which is created in my Macbook Pro so I wanted to sync the songs with all other devices, iPod works great but the Spotify application in Mac Mini keep saying list has been downloaded but each and every song is like disabled and message says "Spotify can't play this song right now. If you have the file on your computer you can import it".

Here are the steps I followed to trying to solve (tried different times),

* Deleted application and installed again

* Restarted Mac Mini

* Deleted ~/Library/Application Support/Spotify/PersistentCache/Storage and restarted application

* Turn off and on back WiFi again

* Created SOCKS proxy to hoping help to sync

There are two file that indicates SQLite database files called mercury.db and mercury.db-wal and the DB has 3 tables in it and one of them is "storage", sounds like location of the files or something. Should I delete these files?

None of them worked. Do you have any suggestions?
