I tryed adding music to my ipod,it said sync.2 ipod but the music wasnt on there whn i was able to take it out

Tick "Manually Manage Music" in iTunes, then drag & drop your songs onto the music playlist(s). Syncing causes nothing but problems, (i.e. if your computer crashes and you don't have your music backed up, the next time you plug your iPod in your music will be deleted.) If you manually manage your iPod you won't have to worry about losing anything.
