Am I correct that the answer to my question is that you are passing an
array of Song instances to the build_all method?  If so, what are you
planning to do that would change that?

I remember from your earlier code example from the earlier thread that
you seem to be trying to define per-user libraries of some kind where
you have one CSV file with a list of songs and another CSV file with a
list of people.  IIRC, your implementation there was trying to link the
two lists via an ID column shared between the two CSV files.

If this is your goal, I don't understand how this will change your
method of loading the songs CSV file.  Yeah, you'll add some fields to
your Song implementation, but that shouldn't require you to move the
instantiation code into a class method of Song any more than your
current implementation does.
