Is Apple music lossless now,5-19-2021?---Can I segregate my lossless 400+ itunes library from apple music while still streaming from my computer,apple tv and iphone. I have had major problems in the past when I tried apple music as it would change my meta data and art work in my library. I don't want to go thru that again. When I use Qobuz,Idagio or Spotify I have no such problems. Any advice?
