MP3Gain might be a better way, I've never tried it but it claims to be able to do a smarter job of normalizing than the peak normalization that EAC will perform. The problem with peak normalization is that it makes your quiet acoustic songs have the same peak levels as your rap metal songs, so you still will be reaching for the volume knob. MP3Gain supposedly does what you would expect would happen, i.e., make them all sound appropriately loud. If you try it let us know how it works, or maybe if Mk4 has tried it he could post his experience.
