How do you get a song off YouTube onto a CD?

You buy the song and then put it onto a CD using iTunes or some other CD burning software.

Necessarily you dont have to buy it. Instead download it off of YouTube using this program (freeware) YouTubedownload.altervista.org/">http://YouTubedownload.altervista.org/ (freeware)
