Well, over the years, the Windows ID Tags were unavailable through Home versions. I purchased a 3rd party tagging software in 2015 to do this. However, I had replaced all my OS on all my home equipment to Windows 10 Pro. When that happened, you can now see several tabs if you right clip properties, including Details, which is available on Itunes, (But you can't add columns), and 2ndly ID Tag Tab, which has a massive choice of additional columns available. So for instance, for some strange reason, my Bob Dylan Album which has 2 discs has all the song info in Chinese. So when I went into the Import CD, I stopped at the Add CD Info, and I was able to add the correct info in a number of columns, but I could not add columns, like Disc. After I imported it, I went to the Windows Explorer view, right clicked on properties, and added disc where I added 1/2 or 2/2, and I added Album Artist, and added Bob Dylan. Now Bob Dylan is quite often the song artist, but sometimes, it is two or three people. If you don't add an Album Artist - ie Bob Dylan, Itunes will separate the storage of each song according to the artists for each song. So an album which is a mix of artists, if you don't add an Album Artist named for example "Various Artists", then each song will have a separate storage which is a consolidation of the Album name and Artist. So some of the older discs with 24 old songs from the 50's, you could never put it back together again. One of the issues with this is that because you cannot add a column to CD Info, you may have to stop after you import it, find all the pieces and individually add Album Artist, and the Info and then it will repopulate, pulling them back together into one spot. But Itunes may not delete the original songs stored individually, so you end up with duplicates unless you go back and look, find and delete them from the library, and when they ask delete or keep, you must say delete on the original one, and then hopefully that copy will disappear. It is an arduous long process. I had 4900 sons and I had already cleaned a lot back in 2015. The other thing is that you must convert from wave or whatever other format over to Apple Lossless, before you clean, as there is no way to transfer those additional columns, on the convert. The information just disappears, and you have to go back into the Windows Explorer version and re-add the columns and data again. The other thing with the artwork, you can only use PNG and JPG. You must use some sort of image software to resize to 1400 x 1400, and then resize the data by compressing it down to about 40 or less KB. Then you can attach it easily, every time. I stored each of these as "AlbumArt_Artist_Album_Name, and stored them in the Custom Artwork folder in Itunes. When you add the Albumn Art, you can search alphabetically then and easily attach them. If you can see it in the directory, the data is small enough. If you can't, the data is too big. I used Microsoft Images from Microsoft Office 2010.
The other thing is I was successful with my sync, although I would not call it that. Firstly, I became aware over the last years I had several computers between the 2015 computer and the 2 I am using now. Each used the same ID. That is bad. So I went into my current computers and renamed them to something very specific like DESKTOP-ZbookB, and DESKTOP-SurfaceB.
The next thing, is that this is achieved through the Home sharing Windows. As soon as I had renamed my computers, up popped a button that asked if I wanted to sync my files to the Iphone which I had attached. I said yes, and under it, there was another button that said to reset my sync history, and I said yes. As soon as I did that, I was able to "what they called transfer" but was actually a copy of the library over to the Iphone. It look about an hour and my original library was untouched, and my phone library has all of the art and everything on it.
So be cautious of the words used. If you have to move your sync button over on your phone to yes, then you will be in a world of hurt when it scrambles your eggs. However, if you use your Home sharing window to achieve this, it is a piece of art. I believe my conversion of every single piece of music to Apple Lossless prevented Apple App from having to make a decision of what to do with it. I think that is why sometime I ended up with dups, as it look the MP3 and created an MP 4 file and left both behind, after I had left it at night. Then I had to go look for the dups again. But once I had completed the entire library conversion, I left nothing to chance.
Hope this helps some other poor sod. I have 256 memory, and 5000 sons were achieved in this format, and I think there was still room left over.
