Script Summary: Enable the built in download function for all tracks so that you can save any MP3 you've uploaded to Google Music with a simple click whilst retaining the correct filename and metadata.
This is no longer needed due to Google incorporating it into the actual site
Click the down arrow next to any song and you'll be given the option to download the MP3 through Google's proper download function which retains the filename and metadata.
Latest script update now will dynamically find the correct links to enable the download option. So it should continue to work even when Google modifies their code.
