the process of converting cd audio tracks into mp3 is called 'ripping'. as only a hobo says you should really get additional software to do this and not use limewire.
my favourite is nero.
click here to download and get information on it!
you do have to pay for it but according to download.com, over 16 million users have downloaded the nero suite. 16 million people can't be wrong can they! if you need any help in 'purchasing' this program *pm* me
plus it doesn't just rip cd's, it rips dvd's, allows you to burn and create dvd with your own start up screen, plus loads and loads more! 5 star product mate!
