10% of BitTorrent users download music – 99% of it is “likely” illegal

A recent survey performed by Princeton senior Sauhard Sahi under the supervision of Edward Felten attempted to discover the types of files available on BitTorrent, a popular file distribution website. According to the study, 10 percent of the shared files contained music:
“For the music category, the predominant encoding format for music was MP3, there were some albums ripped to WMA (Windows Media Audio, a Microsoft codec), and there were also ISO images and multi-part RAR archives. There is still a bias towards recent albums and songs, but it is not as strongly evident as it is for movies—perhaps because people are more willing to continue seeding music even after it is no longer new, so these torrents are able to stay alive longer in the DHT. In descending order, we found that 78% of music torrents in our sample were in English, 6% were in Russian, 4% were in Spanish, 2% were in Japanese and Chinese each, and other infrequent languages appeared 1% each.”
The survey analyzed a uniform, random sample of files “via the trackerless variant of BitTorrent, using the Mainline DHT.” The files, totaling 1021, were then organized based on their file type, language, and apparent copyright status. Before providing their results, Sahi and Felten also explain that their results only apply to the Mainline trackerless version of BitTorrent (admitting that “other parts of the BitTorrent ecosystem might be different”) and that “all files that were available were equally likely to appear in the sample.”
