In order to add music or audio to my iPod, I had to install iTunes on my computer. Easy to do, and from there I simply import any mp3’s that are on my hard drive.
My one problem is I didn’t realize that iTunes doesn’t actually import the file itself and if you delete the mp3’s from your computer, they will still show on the iTunes playlist, but they aren’t really there.
I somehow deleted the audio from my iPod and tried to re-install them from iTunes and I could not for the life of me figure out why they were displayed on the playlist and yet when I went to listen, there was nothing on the iPod. I must have tried five times before I finally realized the files needed a link to the original mp3.
Moral of the story – when you import mp3’s to your iTunes playlist, don’t delete the actual music or audio from your computer.
