MP3 and music video releases are an exception in that they are not packaged into a single archive like almost all other sections. These releases have content that is not further compressible without loss of quality, but also have small enough files that they can be transferred reliably without breaking them up. Since these releases rarely have large numbers of files, leaving them unpackaged is more convenient and allows for easier scripting. For example, scripts can read ID3 information from MP3s and sort releases based on those contents.
