Won't sync local files to iPhone 4S

Hi!

I'm having difficulties syncing my local files to my iPhone 4S. The device shows up on Spotify so that's no problem, however, Local Files is saying "Pending" and nothing happens. There's a picture I've added to show what it looks like. Like I said, my device shows up on Spotify, the only thing that isn't working is syncing the local files since it keeps saying "pending".

I'm currently using iOS6 and I have recently updated the Spotify app.
