    Interface PlaylistGetFocusTrackParams

    Parameters for playlist.getFocusTrack. Report the focused row of a playlist; the same as playlist.getFocusedTrack under its older name, except that a missing playlist fails instead of answering index -1: an index past the last playlist with INVALID_INDEX, a playlistGuid no playlist has with NOT_FOUND, and no active playlist when both are omitted with NO_ACTIVE_ITEM. On success playlist and playlistGuid are always present.

    interface PlaylistGetFocusTrackParams {
        playlist?: number;
        playlistGuid?: string;
    }
    Index
    playlist? playlistGuid?
    playlist?: number

    Index of the playlist; omitted, the active playlist. An index past the last playlist fails with INVALID_INDEX; with this omitted and no active playlist the call fails with NO_ACTIVE_ITEM.

    playlistGuid?: string

    Persistent unique identifier of a playlist (bracketed GUID, case-insensitive), used in place of a mutable index. Mutually exclusive with playlist; passing both or an invalid format fails with INVALID_PARAMS. Fails with NOT_FOUND if the playlist does not exist, never falling back. Invalid-format and not-found failures return the given GUID in details.playlistGuid.
