How many songs can iPod shuffle hold?
Up to 120 songs on the 512 MB model and up to 240 songs on the 1 GB model (based on 128 kbps AAC files at 4 minutes per song).
When the option to "Convert higher bit rate songs to 128 kbps AAC" is selected, are duplicate files added to the iTunes library?
No. The 128 kbps AAC versions of the files are not stored anywhere on the computer.
When songs are transferred to iPod shuffle, is artwork stripped from the files?
No. The exception is if you select the "Convert higher bit rate songs to 128 kbps AAC" option, the artwork will not be included in the converted 128 kbps AAC versions of the files.
Is it possible for iPod shuffle to play music when connected to a USB port even if it's not mounted or in disk mode?
How can I tell if iPod shuffle is charging?
Eject iPod shuffle in iTunes, but leave it physically connected to the USB port. The front LED should be orange if it's charging (or green if it's fully charged). If it's not charging (such is the case if it's connected to a low-power USB port on a keyboard), you won't see a front LED.
