basically, you want to get your songs from say a folder, onto your ipod? okay, first thing is to load up itunes with your ipod connected. then click on the ipod tab, you want to choose the option that lets you manage songs manually.
then drag the songs from the folder, to your itunes library or straight onto your ipod. if you drag them into your itunes library, you will get the option to convert any song the ipod wont be able to play, into the correct song type, that the ipod can play. hope this helps. reply if you dont understand any of what i said.....
