I know this sounds like a silly, bs way if having to do this, but what else was I gonna do? Maybe someday Spotify will clear up this issue, but until then at least I have a workaround. Spotify the synced up all the music files with the titles in the playlists. Lastly, I turned off the Mac and went to Spotify on the Vaio laptop where the actual music files are stored. So there they are, all of my current iTunes playlists in Spotify. As of January 2018, Sony will no longer provide support or updates for Media Go. So I get into the Mac and try the import option in Spotify, import>iTunes, and it works. Customer Notice: Media Go support has ended. I did not have to copy any music files over, ONLY the two library files. I then copied the iTunes music library.xml file and the iTunes l file from the vaio to the iTunes folder on the Mac.
If you try to import iTunes Music Library.xml as a playlist itself, you get one huge playlist called 'iTunes Music Library' with everything in it (6000+ tracks in my case) I have a lot of iTunes playlists. All songs associated with Apple Music wont play and music, albums, and playlists that you added to your personal library will be removed. At the moment, JRiver will only import single playlists.
Luckily, I was able to install Spotify on my sons laptop. They could be updated automatically with auto-sync.
So Spotify's ultimate solution was to use the soundiiz method which as I explained was virtually useless. When I clicked on import>iTunes, nothing happened. My initial problem stemmed from the fact that the import feature in Spotify was not working for me on my Vaio laptop. If you have a lot of songs that you store locally which are not in Spotify's catalogue then the soundiiz method for importing is virtually useless, as it does not import the titles that it can't find in spotify's catalogue, and For those of us who have thousands of these such titles, what are we going to do, add them manually? NOT. So I was left basically on my own to figure this out. I'm not why they can't get things right by now.
Well, let me start by saying none of spotify's 'solutions' were completely successful.
