The Jukebox has a skinnable graphical interface and allows users to manage a catalogue of digital music, as well as CD and stream-based audio. It has a fairly advanced AutoDJ but has been noted as having a longer boot-up time than other players. The Plus version includes faster rip and burn times, exportable tables and tech support, as well as a "Super-Tagging" function that fetches for tags and album art and attaches them to the song file, allows you to customize the art and tags for any files in a directory, or rename files based upon the tags already stored in the files. These features, and others, were meant to be incentives to upgrade from the free version, which lacks them. The upgrade is done by entering a serial number which must pass a local validity test.
