Play mp3s on a CD player
Not all CD players will play mp3 recordings. If yours can't, use iTunes to convert an mp3 to the 'AIFF' format and 'burn' it onto a CD in four simple steps.
Now drop an mp3 file into the large Music library window pane (on the right of the side panel). This will install it into iTunes.
Put a write–able CD in your CD/DVD writer.
For a smaller file size, and as an alternative to the above, select ‘Create AAC version’ from the ‘Advanced’ drop–down menu in iTunes and burn that file.
