this is something known about MP3s. they are often in different volumes due to different recording/ripping settings.

first of all you might wanna try to raise the volume in your MP3 player program this way you don't have to raise it on your speakers.

then there is something called volume leveling. some MP3 player (programs) have this feature that they level all MP3s to one volume. musicmatch juekbox features this for example.


the volume will stay different on a CD unless you level the volumes before burning. again there is software (MP3 players and burners) that features this.
