My built-in SSD is relatively limited when it comes to storing all my media files, which is why most of my iTunes library lives in the cloud via iTunes Match, for streaming on demand.
In the near future I'm going to be disconnected from the internet for about a month, and I want to have a offline copy of all my music so I can continue to listen to it, but I don't want to download it all to my main iTunes library.
How can I create a separate, offline library containing every song I have in iTunes Match?
