I have spent a little time experimenting with different ways to manage music in my new SHO. So, I though I would pass on my learnings, to save people some effort. I was a little excited to have a 10GB Jukebox to play with, and wanted to get some of my (120GB) MP3 music loaded. I quickly discovered that the 10GB jukebox is virtually useless (to me), since all you can do is insert a standard CD (not MP3) and rip it onto the hard drive using the Sync "record" button. The inability to load MP3's from a DVD/CD/USB was very disappointing. I decided that if I couldn't get my music on this way, I would abandon the Jukebox and leave it empty. Next solution: 1) USB Thumb Drive The USB thumb drive worked very well and displayed all the basic MP3 tag information (song name, artist, album). It also supported "folder mode", allowing me to put different music into different folders, while showing me which folder the music was residing in. Ideally, I would like to put different playlists into unique folder. But, I was not able to find a way to tell the audio system to stay in one folder, or to quickly jump from one folder to another. - If anyone has figured this part out, please let me know. 2) CD / DVD disks I tried copying MP3 files to blank disks using the standard Windows 7 utility. The Sync system did not like these disk and rejected them as "incorrect format". However, when I use iTunes (V 10.3.1) to "burn playlist to disk" I found success. BOTH CD-R and DVD-R disks worked. This means that if you use a DVD, you can get 4.38GB of music onto a single disk. MP3 tags are displayed, just like they were with the thumb drive. But, since iTunes will only burn one playlist at a time, you are limited to burning separate disks for each playlist. Not the end of the world. As an aside, I also used a free utility from DVDVideoSoft called "Free Audio Converter" to resize my MP3 files, allowing me to put more music onto a single disk. It is a great utility. Hope this helps someone.
