Okay, that makes sense. And yes, I do remember on a wired sync it does the same thing.Hmmm ... it always wants to sync the (m3u) playlists even when there have been no changes. I synced and then immediately synced again and the preview shows the same playlists that were just synced.except for a brief period, its always been the case the playlists are always copied. I dont think i will change that
For the future: show the total number of tracks to be synced. I can't remember if MB does that on a wired sync, but on a desktop it's fairly easy to get a sense of how many tracks will be transferred. It's more difficult to sense on a small screen.
