I added a Smart Playlist (album name & last played=before today) and noticed it would skip a few tracks. At first I thought this was due to the Shake to Shuffle feature, but it happened again once I had that turned off. I also noticed that the screen would say "Playing track 9 of 5" instead of saying "Playing track 5 of 9". Anyone else experience this? I haven't tested it on a regular playlist yet, but it's happened three times on smart playlists.
