The MPST Digital Jukebox software is based up two incredibly cool pieces of software written by Mike Oliphant called DigitalDJ and Grip. These sources have been heavily modified and combined.  Unfortunately, the databases are no longer compatible, but the changes are very simple. The latest source code for The Digital Jutebox can be download from here, but it's still in BETA and not in a very friendly format yet.  Some functionality is still missing.There are also many other packages you will need which will be outlined in detail in the HOWTO document, which is still in progress.
