Follow the steps in this post to see if they help. If your mobile doesn't even show under "devices" in the desktop client, temporarily disable all firewalls, security and antivirus software on your desktop and make sure that UPnP is enabled on your wireless router.
So here is a last resort type of solution that I think might work. Go onto spotify on your computer. Take the playlist that is acting up. Copy all of the songs in the playlist. Create a new playlist. Paste the songs from the original playlist into the new one. onyour ohone, witch the new playlist to be available offline.
This takes a little effort, especially if you have many many many problem playlists but this should work.
so what are we supposed to do when our files wont sync? i have music from my computer and it wont even let me play it unless i sync the playlist into offline mode. when I try to sync into offline mode nothing happens? HOW AM I SUPSSED TO LISTEN TO MY DOWNLOADED MUSIC! HELP!
Edit, yes I have a premuim accnt, yes i have 1.5 gigs available.
Hi! Thank you for your time as I have had the same problem and as of yet have not found the solution in this thread. I can download it seems like a very specific number of songs, and then every song after that has a red exclamation point by it and won't download. I have 16 GB of free space and I believe at the very most 700-750 songs. Thanks!
