The legit channels have a level of convenience now not seen in the piracy channels, because money pays for proper curation and surfacing of content. I used Limewire back in the day. I couldn't tell you how many songs in my collection were artist credit "System of a Down." I think I had a System of a Down copy of the 1812 Overture in there somewhere. (It is also possible that legit channels are over-counted in the data because they're easier to explicitly audit. If the error factor estimate is the same for legit and bootleg channels, the data will reach the wrong conclusions).
