Winamp had this stuff figured out years ago and did it in about 200k. If you absolutely want to force i Cloud Music Library to re-sync all your music, turning it on and off is the way to go.I'd recommend this step for anyone who is experiencing freezes or hangups when trying to sync with i Tunes Match or Apple Music, especially if you've already tried all the above steps.
