Sorry Jemmiffer as I hinted I probably don't have enough experience with this issue why it's just as well Peerless answered it for you. I can't remember whether they normally play sequentially or not & I don't use the playlists within LW. Playing them straight off the shared list they seemd to just play one at a time (though I'm sure that's not always the case - it was this time for me.) So just ignore my points.
