I can play a certain playlist offline perfectly when I first connect my ITouch to Spotify in my car when I leave home. Recently, though, when I try to reconnect in my car later, only certain songs on the list are "active." The rest are greyed out. The active songs are no older than the greyed out ones and all of the songs have synced and played before, both when I first connect and every time after. I have lots of storage left, so that's not the issue. And other lists are fine. It's my largest list set to play offline, but I'm nowhere near the limit, either. There are only 366 songs in that one, and the others are a fraction of that. And there are only three set for offline play.
