In my experience anything sound related breaks in editor mode if you start the game and then pause it and start it again. This goes for ambient sounds and such as well. Tracks will play all the way through if you leave a trigger but the playlist will stop and not switch to the next song.
Another thing you can do with sound is add ambient effects to items and not just triggers.
Have you run into any playlists that simply don't work at all? I haven't tested them in game much at all but in the editor this is the case.
