Hello! 
I think this is what I need to do as well!
Would someone please show me the blocks that illustrates what you’ve said to do here:
“Have a variable to store the original list and whenever you want to restore it just assign this variable to the listview.items property.”
My app pulls in tracks to play into a list, then deletes them as they’re played. It stops playing when they’re all gone, but my goal is to have the list to refresh once it’s empty and replay (x infinity).
