Update requested of existing mod - DJ plays custom music

A very nice mod that i sincerely miss. It is free to maintain, authorized so by the original creator. Besides adding your custom music to the dj booth it provides a set of speakers that can all be linked. Could someone update this? I unfortunately have no idea of how to do that. :(
