How the heck do I burn Audio to a CD-RW?

I got some CD-RW cd's

Brand: memorex

there labeled as High Speed CD-RW 12x 700MB 80min

Ive tried everything and i just cant get the audio files to copy.

Ive tried using itunes , windows Media Player, and some other 3rd party software and none of them seem to work. Ive tried three different computers all of which Im pretty sure have cd burners in them. the drives say compact disc rewritable on them which I assume means they can burn CD-RW.

Some times it will complete the burning proccess and say it was succesful but when you pop it in a cd player you get nothing. Sometimes it will say that there was just and error and the burn could not be completed and other times it says that the disk may be broken or damaged or you should try a different brand. Ive tried 5 different disks and there brand new so I don't think broken or damaged is the case. Could someone please provide some insight as to what it is im doing wrong.
