Spotify no longer working on iPhone

[Sabahansari]

Hi my spotify isn't working on my phone anymore. It just shows the playlist names and says 0 tracks and upgrade to premium, which I'm on?? I've tried logging out and I used my username... Any suggestions?

Sabahansari - It looks like your most recent payment hasn't gone through. Unfortunately, I can't really see why. In order to get your Premium up and running again, you'll need to resubscribe. Just head here to do so: http://www.spotify.com/account/subscription/
