I do as you intend, burn MP3's on to a CD for use on an MP3 player. With MMJB Plus you can burn either as audio or data. You can normalise the volume (they call it volume leveling)and then burn as data. If you have an MP3 player that will play MP3 Pro you can even convert your MP3's to MP3 Pro. That way you can get twice the amount on a CD. The current cost online is either £13.26 for the current version or £26.52 which includes all future versions. Have a look at the site.
