You are able to place an Ots Album file into the playlist to have OtsAV begin playing the items, within the Album, sequentially.
Select the Albums tab in the Media Library area.

the album you want to play. The first item in the album will begin playing
instantly, and the remaining items will be sequentially added to the playlist.
