Okay, when I rsync everything, and then go to emplode or jemplode and sync, it trunicates some of my playlists. It iwll take my current total of songs from say 186 to 94. If I do not do this then some of my songs will refuse to play and then freeze the player if I try to shuffle or select a new playlist with those songs "active". I sync it with emplode and/or jemplode so I can get my mp3's in ABC order on the player.
