Itunes Library Problems (iCloud duplicates library)

Thank you. Unfortunately, any articles I originally found weren't pinpointing the problem to the iCloud Music Library and were just recommending the use of the "Show duplicate items" menu under File -- Library, regardless of using "iCloud" and other relevant search terms in my search. I knew that had nothing to do with the problem. So, mostly solved, but not quite. Some purchased files still have the download symbol beside them even though they are already downloaded and living on my computer. And I still have to re-organize most of my music library back to what I want but I am much better off and much less frustrated than I was before. Thanks again for the help.

Actually, I spoke too soon. My problem isn't solved at all. I did exactly as the article recommended. I verified that the iCloud Music library was turned off. I logged completely out of iTunes. Looking at my library, on first glance, under the first artist it seemed to be fixed. But no such luck. Now some albums have 3 copies of each song, others have 2. And some still have the cloud symbol, but instead of it appearing beside each song it's at the album title. Some copies of the song are greyed out in the list. So, I tried deleting the greyed out copy of the song. You would think that what was greyed out would be the "bad" copy. Nope. Won't play. Restored them. The greyed out song is the one that will play on iTunes, and the other one will not. Now I get the fun of going through my entire library to see if I can restore my library to a usable state. And I've already spent close to 4 hours on this. I've had iTunes since the beginning and though I have had the occasional problem, I've managed to solve them up until now--Is this what the future holds once they make their switch and completely shut down iTunes? Unbelievable. As of now, my music that I've paid thousands of dollars for over the years is currently unusable. I appreciate that you tried to help, but it didn't work.

Can't argue with you--Definitely a problem somewhere. But I really do appreciate you taking the time to try to help me. And I have all the information you provided saved in case something like this happens again. Gives me a good starting point to solve the next iTunes catastrophe! I apologize if I took any frustration out on you--Having "one of those days" and this was the just the last straw. Cheers, and thanks again for you help--You're great ... iTunes, not so much at the moment :)
