iTunes has an option that I've used often in the past, I believe it was named Remove Download, to "undo" the download of a song or album (I've used it to free up space and to re-download music into different folders). However, I no longer see the option to do this, and I can't figure out why.
I'm using macOS Mojave 10.14.6 on an old MacBook Air. I'm not subscribed to Apple Music or iTunes Match (subscribing to either one is not an option right now). My account is set up with Family Sharing.
Thank you!
