How to undo the "delete song from iCloud"?
Acidentially, I have apparently deleted my entire library from one of my macs. On my MB Air I only keep the songs I need because of limited space reasons. When I need more space temorarily I delete the songs in iTunes locally but not in iCloud. This way I was always able to re-download them. Just now I overlooked that I had deleted them already and apparently clicked OK when it asked me if I also wanted to delete them from iCloud?
How can I undo the delete songs from iCloud?
What is the best procedure now?
iTunes-OTHER, OS X Mountain Lion (10.8.2), iTunes Match
