How do I download all purchased music at once?
I'm using iTunes version 12.1.1.4 on Windows 8.1. After hours of trying to figure this out, there is seemingly no simple or convenient way to download all my purchased music with a single click. The "Download All" button in the bottom right of my purchases window will only download what is selected in the left pane, and I cannot find a way to select everything at once.
