Go to www.apple.com and download itunes, put a cd in your computer and click import, it will transfer compressed MP3 files to your computer, you can set the size/quality in the preferences 128k is standard, 190k is better, 320k higher quality... Also check out the Music store, you can click on a song to hear a sample and then buy it for $ .99 or the whole "CD" for $9.99. Then with an ipod, just plug it in to a usb or firewire port and it will sync all of the songs in itunes to your ipod assuming it has the capacity.
