The word torrent has become synonymous with illegal internet activities but in the whole spectrum of internet downloading it is an incredibly efficient way to share files and perfectly legal. It just so happened that early adopters of this new tool used it to share copyright protected content which in turn is probably the reason torrents took off in the first place. Many sites will use various torrent services to distribute content to reduce server loads which in return gives the user a much faster download than traditional linear based downloading (assuming the file is being seeded by many people). Nine Inch Nails used this to their advantage and not only saved them money in bandwidth costs but allowed the user to download a high quality album within seconds.
