I have iPhone 4 with iOS 7 and a premium account. The songs on the album appear to be playing but the track playing time doesn't appear at the bottom or if it does, it doesn't go forward. Even stranger, when I viewed Spotify from my locked screen mode, the track time was moving but there was no sound. This was only on the locked screen and now it doesn't even do that. I've tried uninstalling and reinstalling the app but it doesn't help. I logged onto my account with my boyfriend's phone and then everything worked fine. I have no local files or whatnot in the app.
Btw I'm using free mode. But this issue is limited (for what I've been able to understand so far) to one album. But the behavior is just like described. On lock screen seems to be playing and the time is counting. On the app does not show time and has the pause button like it was playing.
my problem got fixed today, deleted spotify from my phone, and deleted the playlist from the computer aswell, waited about 30minutes or so. when i downloaded spotify again, the playlist worked 🙂 maybe this will work for you guys aswell?
