Well sure, but it's all supply and demand. If someone was selling a song for a hundred bucks, I don't think I'd buy it. Ten dollars, in very exceptional cases. One dollar without much thinking.

Also, we're talking about Masters on BlockTunes. Owning one will give me passive income every time someone listens to that song. The amount is dust, but over time it could accumulate. That's it, though. Owning a master does not give me any commercial rights, does it? I don't even think I could incorporate it into a video I create, without at least asking and coming to terms with the musician who created it.
