We use to be able to easily synch local files by just dropping them into a Playlist on the desktop app and then downloading them on the Android app. Worked perfect. Now when you do this the songs wont download. They just show as unavailable and grayed out. I've updated the app fully and checked file formats and encoded them to specific files for spotify but nothing seems to work. Every workaround and forum I've checked I've done every which way. Ut there has never been a defentive answer or post in like 2 years that has any sustanance to any help. What should take 5 minutes has taken 5 hours for 2 songs. What do you have to do to play your own songs on spotify for android?
