in a nutshell , ipods suck for one very reason
they do NOT use/play mp3 files in a native form
example
you get a mp3 file from the internet, you cant just drag/drop into the mp3 player (once you plug it in , it normally shows as another drive in 'my computer')
an ipod absolutely requires that you use itunes.....to convert it to apple's format
the easiest way I can describe 'getting music into them' is
you get a software that 'transforms' your cds into mp3 files (real player, media monkey and others)
this will allow you to 'copy' your cds into the harddrive in your computer (with a very small reduction in quality, you can use several kbps to encode them , 128 is not cd quality but good enough, 192 is very very close so that you couldnt tell if its a cd or not)
anyway
you end up with a bunch of files in your computer (one file / song)
you then copy/paste from your harddrive onto your mp3 player.....and play them
