I recently starting using the new generation iPod Shuffle and found an interesting difference between this second generation model and the original shuffle. In the original shuffle you could easily select a playlist or playlists to sync with the device, or fill the device automatically. The new generation model has a similar feature but it is more disguised. On first glance I thought I could only manually add songs to the device, but you can tweak the autofill feature to grab a specific playlist. With that feature you can deselect the random fill feature which is checked by default, essentially allowing you to sync a specific playlist with the device. Just a quick tip if you are looking to manually control the music going to your iPod.
