Apple Music Library suddenly not available

I purchased a 16 Pro Max in Dec 24. Now I realise I've lost a lot of money that I had purchased! Which in my opinion feels like theft!

" This item is not currently available in your country or region"

which I find incredulous as A. We are talking about big bands like AC/DC or Coldplay, B, I purchased music so regardless of what Apple thinks, I purchased music in the country I was living in.

why suddenly now!!??

Apple, will you recompense a devout Apple user?

any workarounds?
