Per your article, Kirk, Apple is going to use the iTunes Match algorithm to power Apple Music. http://www.macworld.com/article/309...tching-ditches-drm-files-for-apple-music.html I deleted one previously matched tracked whose iCloud Status was "Apple Music." When re-added, it says "Matched." So I suppose my account is now under the new algorithm. Because of the old algorithm, my iCloud Music Library is riddled with mistakes. I have hundreds of tracks that were live bootleg versions that Apple matched to studio versions. How do I nuke Apple's cache of my library so that it does a complete new scan + match or upload of my library without also losing all the songs I've added to my library via Apple Music (songs that I don't own but added to My Music via Apple Music's catalog).
