Since you guys wouldn't give the other once a helpful answer I hope you'll finally take your te and listen/read this.

So for 2weeks I've had the same problem, my tracks starts playing but stops again at 1minute, and it doesn't stop in a way that it isn't synced, there just the music that stops coming an the play button is still there (as if it's playing normally).
I've tried:
Reinstalling spotify
Restarting my iPhone
Synced with my computer
Restarted my wifi/Internet
Used offline playlist (all tracks fully synced)

So where is the real problem my dear spotify crew? I've tried all of the stuff you've told me and others. Nothing helped anyone of us. I'm so furious I could probably throw my iPhone out of the window, I miss my daily music. Don't ignore this problem like I've seen some other posts getting ignored.. It's a great concept that you're having with spotify and it's just truly sad that my spotify havnt been working properly for about 2weeks.
