Invoke default mp3 player on Windows

[Shao Sean]

In Rev 2.7 and greater they have added a new command to supplement the 
"launch" command and it is called "launch document"

--- snip from the documents --

launch document allows you to open the file <filename to document> without 
specifying an application.
The document will be opened using the standard shell association on Windows 
and Launch Services on Mac OS X.
This means that launch document will have the same result as double clicking 
the file in Windows Explorer and Mac OS X Finder.

-- end snip --
