9/10: In the version of MusicSearch.java that was originally 
  installed on the home page, the method processTitleSearch
  did not compile, because it was calling albumByTitle instead
  of albumsByTitle.  The fix is to add the "s" to the 
  method invocation, but also change the next few lines
  so that they can handle a list of values, as is done for the
  other searches.

9/15 Modified the comment in MusicDB.java for albumsByTitle to 
  clarify that the method returns a List (related to the above
  point), not an Album.
