And I'm really interested in whether his streams were actually the source of the files. Most private torrent sites are really particular about quality. I don't think a song normally streamed would normally meet those qualities.
Also, I'm sure the song was not streamed in a lossy format. So song data would have been lost. And while you can convert a lossy format to another format, it won't be as high quality as if it had been converted from a lossless format. And there are signs that an album has been transcoded. And most private sites also have problems with transcodes.
So if other, non-transcoded file versions were released on the internet, and the stream was a lossy format, I'd really have a hard time believing he was the only link.
