I believe that no one knows how to fix this but since there is no real spotify support I need to give it a try.
Any ways Im on a free account and I have listened to a track 5 time so it gets unavailable.
But the thing is that it shod get unavailable for like a mouth I think.
But it have been unavailable for more than 5 mounts.
Im getting pretty irritated.
Do some one know how to solve this?,To me it sounds like a bug in spotify.
