People can get what is popular. There's just so many albums and soundtracks that just can't be found on Spotify. Legal streaming is nothing compared to the private music torrent tracker scene... Before it was shut down, one particular site was often called the library of Alexandria for music and even had actual artists release their music there.
What CD was a private music tracker. It's hard to describe the range of music that was there. And there was a huge community that really knew its music so you could discover some really cool music through collections and the forum.
Redacted is the tracker that rose up as it's replacement after What CD was shut down.
I don't get peoples obsession with only using acronyms when you can just Google "<acronym> tracker" and get the name.
Googling "RED interview" should provide you with an alternate pathway in, however.
