How do I overwrite metadata for my iCloud Apple Music?
To be more precise:
My music library on my desktop is the main library from which I want all my devices and other computers to feed from. This means I would like my iTunes in the iCloud to reflect exactly what I have on my desktop (album title, album artist, artist, composer, genre, artwork).
After months of trying to get my 25k+ song library to work properly, and hours and hours spent on the phone with Apple's tech support, I still have a few problems:
1) Art work, genre, and some other meta data on many of my songs is incorrect, as is sorting.
2) There are still quite a few songs that have the meta data and artwork for another, completely unrelated, song (i.e., a Rolling Stones song will have the Beatles meta data, which indicates to me that there is something wrong in the file storage in the library, but that's for later).
3) Songs that had been burned by me onto my hard drive (legitimately, for those asking) still need to be downloaded from the iCould, even though the file exists on my hard drive.
Any feedback is appreciated. Also, is there a master-level iTunes class or book someone can direct me to? I am familiar with all basic iTunes skills (I think), and need an in-depth tutorial.
iMac, OS X Yosemite (10.10.4)
