It's not drastic .
it's based on the fact that I'm pretty old , liked iTunes , had software that could do what I wanted (that I paid for) e.g. cross fade on the fly . I just want to buy / own songs and use them how I wish e.g crossfade at any point in the track.
This has been replaced by Apple Music which I enjoy but doesn't do what I want it to do . And furthermore apple is preventing me from using software I wanted to use with my old iTunes songs and I can't do that now either.
The only reason I can see is they didn't like third party apps offering functions that they won't offer themselves because of control freakery.
preventing crossfade when it's perfectly possible is bad enough , but when you make your devices unable to do things that they could do previously is retrograde / bizarre.
as I play music in function halls I can no longer use my Apple devices to do this, so it isn't a case of me having a hissyfit , just a reality
