Why does an MP3 file not sound the same as the same original music played from a CD or a tape?

you probably need to change the kbps which is the sound quality if you put this at a variable of 85 to 145 you will get CD quality. to do this on Windows media 11 when you rip you click the arrow to do this on the older versions you go to tools and then options and click the copy music sign.(you will have to re rip)

if this does not work then your CD drive might be busted.
