how to use the mp3 part of a CD? you know like a Cd player with mp3 capabilities??

Answer 1

This just means that if you save a bunch of MP3 files to a CD (or possibly a flash drive, depending on the CD player), your CD player will be able to read them. If you burn a standard music CD, they will probably not be in MP3 format, but rather the standard CD music file format, which should be playable on a wider range of devices.
