Missing purchased music from Library.
I have noticed throughout the years that my itunes library has been missing songs that I have purchased through iTunes store. What is strange is that the songs and albums are no longer in the iTunes store. The appare to have been deleted. For instance, Prince, just after he died i purchased (The Most Beautiful Girl In The World on the "Gold Experience Album") and now its no longer in the store so when upgrading and restoring my iPhone and using iCloud there is no more song neither in my itunes library on my pc or any of my apple products. In my estimate I am missing over 200 songs that I have paid for and no longer exist. In my Library there is the space and title but no data of the song. Has anyone else have been experiencing this kind of thing? I have been using itunes from 2007 and have spent a small fortune collecting music on this platform and need a straight answer as soon a possible. Thanks in advance.
