When you load a new song, the current one is closed, assuming it has been saved. If it has not been saved, you will receive a warning asking if you want to save it before loading another. In either event, no song file is left open.

Of course, as with any computer file, if you haven't saved it and your computer crashes, you may lose the unsaved changes or get a corrupted file (rare in BIAB, in my experience), so save your work often.
