How do you transfer mp3 files from your PC to your IPod?

Your iPods charger can be plugged in the computer as you already know. Then iTunes pops up. DO NOT CLOSE IT. Go to start and open your music folder. Go back to iTunes and start a new music folder. Find the music you want in your other music folder. Right click, copy. Go to the other music folder, right click, paste. Keep doing this until you have every song you want. Then click sync. This may take a while but when it's over it's time to have fun.
