MUSICMATCH Jukebox was developed by Yahoo. The software ran on Microsoft Windows and managed digital music collections and playback.
An .mmjb_mime file contains data used internally by MUSICMATCH Jukebox. It is not a user media file and is not intended to be edited directly. Its MIME type is application/x-musicmatch-mmjb5.20detect.
MUSICMATCH Jukebox and the .mmjb_mime format are obsolete, so these files are unlikely to be useful with current software.
An .mmjb_mime file is an internal MUSICMATCH Jukebox data file rather than a document intended for direct opening. If the original application is installed on Microsoft Windows, it may use the file automatically.
Modern media players and text editors are not expected to interpret this file correctly.
An .mmjb_mime file contains internal MUSICMATCH Jukebox data rather than standard audio or document data, so it generally cannot be converted meaningfully with standard conversion software.
