So, they don't actually want anyone to listen to it?
You can buy it on the digital stores like Bandcamp and iTunes/Amazon but you can't stream it like with Apple Music or Spotify, Etc.
You can listen to it on Bandcamp up to 3 times while the rest of the stores only have 30 secs previews. I'll be using Bandcamp to listen to the album and see if I'll buy the album (which I think I will, I have all the CDs).
