From my experience using Ubuntu, neither rhythmbox nor banshee will automatically see the clip. The solution is simple.
Create a file in the root directory of your clip and call it
Open the file and insert the line
That’s it. Unmount/unplug your clip and reconnect it. Banshee and rhythmbox should both now see your clip and you can easily add music directly from your favorite media player.
That’s my trick I learned today and I thought I would pass it along.
