Digital music that you purchase hasn’t had DRM for over a decade.
there are lots of countries where you can not buy DRM free music from amazon (afaiu what the OP was referring to)
so the problem is how to find a shop where you can buy your super rare tracks ...
(i assume some will also be bootlegs or other fan-made recordings - you wont find those in a shop)
Yes, I know that fortunately there are many ways to pay for DRM-free music (I mentioned that I use Bandcamp pretty often). What I miss is the vast amount of content I had available 10 or 12 years ago; I have been able to buy a lot of music, but there is much more that just isn't available.
