The appearance of "repack" alongside an MP3 search is notable because MP3s are already heavily compressed audio files. Unlike a 50-gigabyte video game, an MP3 of "Dreams" requires no further "repacking" to be efficient. The use of this term suggests one of two scenarios: either the search engine optimization (SEO) tactics of piracy sites have blurred the lines between media categories, tagging audio files with popular software-piracy keywords to drive traffic, or the user is looking for a specific, curated archive—perhaps a collection of the band's discography compressed into a single RAR file. It transforms the song from a piece of art into a piece of digital cargo, stripped of its metadata and context, traded purely for the efficiency of the transfer.
