I am curious if people have taken the opportunity to replace the files in their own music libraries with the ones from Apple Music? Either to save hard drive space or to get a newer version of some particular album. (After making a backup of your original files of course.) I thought about doing this - especially with the large number of my live albums that were mis-matched by iCloud Music Library. My only "concern" would be those times when the streaming from Apple Music is in one of it's "slow periods", which fortunately I have not experienced a lot of.
