Further experimenting found two other solutions.  The first is to use:
a=Dir.glob("C:/Users/Public/Music/Sample Music/*.wma") which has the 
same "problem" as my first solution.
A better solution may be to use Dir.chdir to change to the directory and 
then use Dir.glob to extract the file names.  This has the advantage of 
not including the path in front of each file name.
