I want to keep my iTunes library on my hard drive and maintain a synced copy online which mirrors any changes made such as new music, deletes, plays, ratings etc. What cloud service can do this for me? I've spent ages googling this but nothing seems to come up that meets my needs - it all seems to be about changing the location of my library so that iTunes points to the cloud and that's not what I want. I tried OneDrive but in order to copy my library it seems I need to have enough disk space to duplicate my library in order for it to copy and sync with the cloud.
