You can test all the alternatives and decide for yourself. Your answers are some 2!N in quantity so there is no true single answer since even in MP3, you could drop the bitrate and the filesize will drop.
But that may not be the measure of your success.
Hi everybody. I have MusicMatch on my very old PC and it runs fine. What I would like to know is, is which CD ripper is better and which will create files that are smaller that MP3.
