problem with downloaded spotify-playlists on iPod

[user-removed]

Hi,

I have a spotify premium account. I have a special directory for playlists that I can listen to in offline-modus on my iPod. Parallel I add and remove playlists to and from my special directory on my PC. When I charge the battery of my iPod (approximately every 2 weeks) I also put the iPod online and sync my playlists. The playlists that were downloaded ("local"?) and that I want to keep in my special directory should stay downloaded.

That's were i have a problem: Sometimes it does see my previous playlists as "downloaded". Sometimes it sees all playlists as "not downloaded" (even when they were downloaded) and it starts to download all playlists again.

This is very irritating. Any solutions?

regards, Jan
