Itunes icloud sync post clean up
I have ripped a number of CD's and also music purchased and cleaned up or organized using meta tags (apple meta). If I turn on cloud music library, the documentations says:
WARNING: After you turn on iCloud Music Library on a device, all the music that’s currently on the device is deleted and replaced with songs from iCloud. Also, you can’t use iTunes to sync music with the device. You can add songs to the device only by downloading them from iCloud.
1) Will this delete ripped music and purchased HD tracks outside of apple itunes?
2) Will this overwrite my organizational work? For example using Album and song info, I have organized (largely classical) by composer instead of conducter.
