Wow, I think that's wildly off the mark. Bob Dylan probably has several billion streams per year, if not more. On Spotify right now, his top 10 songs have a billion streams. Obviously those did not all occur in a single year, but Dylan's catalogue is deep, and Spotify is hardly the only platform.
One billion streams per year is about $4 million on Spotify.
The big revenue comes from film and advertising licensing, we saw this when Michael Jackson (who owned the Beatles back catalog along with Sony who he was in a vicious battle with).
Despite the claims in this article, Jackson didn't sell out many Beatles songs, it was Sony after he died who enabled and profited from Beatles songs in commercials and films. https://www.biography.com/news/michael-jackson-paul-mccartne...
