Why are some songs louder/quieter when playing from MP3 disc or player?
When converting (or ripping) audio to MP3 format, one has the ability to control or modify the quality and volume of the source. Depending on the settings of these options when the files were encoded, one may be of greater or lesser quality and/or volume when compared to another. You may find more detailed information by searching the Internet for “MP3 FAQ” and “MP3 Standards”.
