Not sure where to post this, but... How do I add music to my iPod Nano? >_>

Yeah Khoi, you can just use iTunes. Just download it from the iTunes site and then start importing music from your music folders. Some songs (like those in WMA format) it'll convert to the m4a format, but you can change that in settings so it'll convert to mp3. mp3 format songs don't need converting at all, they can go straight on your iPod. You can still use the songs you have, you don't HAVE to buy songs from the iTunes store. Hope that helps! <3
