How to prevent iTunes 12.2 from automatically uploading sound tracks to iCloud Music Library?

I've notice after I updated my iTunes to 12.2 on my OSX 10.10.4 computers, a very large upload bandwidth has been taken place. This is a result of Apple's new iCloud Music Library feature. I don't want to upload my musics to iCloud, and I found no options to prevent iTunes 12.2 from automatically uploading sound tracks to iCloud Music Library.

I also noticed if I use file > library > Update iCloud Music Library, some of my deleted songs will come back to my playlist. I can delete them but once I click file > library > Update iCloud Music Library again, they will reappear in my playlist.


To turn off iCloud Music Library on your mac, you need to go to: iTunes>Preferences>iCloud Music Library
