How to buy music?

It's frustrating to live in a world where streaming is the main way to consume music. I found this German band from Berlin called "Von Wegen Lisbeth" because of their son "Wenn du tantzt" which has great music and great text: https://www.youtube.com/watch?v=m2JRghbgeYw

So I was thinking, it would be cool to buy the Album so I can listen to it. I normally buy and listen to albums not singles. But where do you buy it digitally? I don't want a CD or Vinyl because I live in Korea and I will need to move and don't want to deal with physical media.

I thought, in the past I found music on Bandcamp, so I went there and found https://vonwegenlisbeth.bandcamp.com but there they only sell their first album which doesn't have the song on it.

On their website https://www.vonwegenlisbeth.de/ they link to a shop where you can seemingly buy all their albums: https://krasserstoff.com/vonwegenlisbeth#merchcat-vonwegenlisbeth-musik butonly on Vinyl and CD, not for download.

Then I thought perhaps I could just pirate it, but the band seems to be too small, they don't show up on The Pirate bay.

I checked Spotify and all their albums are there, but I don't want to pay a subscription every month.

Isn't it weird that you can't buy a digital copy of a bands music? Where do people buy music digital copies nowadays?
