The object are still not being added to the array correctly, they are inline
or just all the same object and everything seems to be going wrong. I know
the first half of the code works for listing the files tags and it works
exactly as it is supposed to (though it could probably be done better). The
only thing that the bottom portion of the code needs to do it create a new
array for each album and update as it goes along through the list of files
and add each small array to a big array. What is structured so badly that
makes the whole bottom portion go horribly wrong?
