Thank you for your thoughts.
Unfortunately, I am aware of the difficulties with the cloud and the many players in the technology not working well together.
And yes, I went to great lengths to shut off activity related to any music completely and to remove my music files and anything Apple from the One Drive app and its folders prior to this exchange.
I uninstalled iTunes, deleted all of the folders and Apple extensions then reinstalled iTunes. I then copied cut and and pasted the artist folders into the new iTunes Music folder. I deleted the Genius extension.
Hopefully this will have cleaned everything up. iTunes had some work to do adding the artist folders back in. I’ll check on it this morning and see if the error was resolved.
Just in case, I still completely backup my approx 250 GB of music to old tech external drives and to a Linux internal storage SSD and music software.
I wish it wasn’t an issue. The majority of my music listening is via Apple Music played on a network integrated Marantz amp with a decent built-in DAC and with an iPad as the source.
Thanks again for your help!
Cheers!
