Windows Phone App doesn't seem to dowload the songs in the offline playlist, instead it is only downloading when the song is played at least once. Is there anyway to select and download the songs you want offline?
You are right. When I noticed today morning, I saw the progress bar just beside the playlist showing download progress. I have no idea how the donwload started. Hope it did not consume any 3G data connection!
Any insights from the Spotify team would be very helpful to understand this issue.
