> have you used Apple Music and has this feature failed you?

Absolutely. I have a number of mix CDs (above and beyond, mainly) where apple music has apparently looked up the songs by title and artist only and replaced all the tracks in a mix CD with single versions of those songs, needless to say not mixed. I also have other songs which simply refuse to sync.

The article says: If you subscribe to both iTunes Match and Apple Music, then iTunes matches your songs using digital fingerprinting - but I thought Apple Music included iTunes match. Do I seriously have to sign up for another product as well to get this working? Not very impressed.
