Another thing you can do is directly copy the music files that already exist on the disk of one of your empegs. No need to do a music-load if one of your empegs is already loaded with music.

Instructions on how to do a drive-to-drive copy are in the disk upgrade guide. Essentially, you just copy the contents of the drive0/fids folder, put the disks back in the proper players, and synch once to force a database rebuild.
