A little tip (and maybe a request for quality control?)

As an article found googling for volume wars explains, there can be a 
problem with clipping of the peaks in the music, creating clicks or 
worse artifacts in the sound. That was the reason I started using 
vorbisgain. Some music I listen to varies a LOT in volume throughout a 
tune and the result was terrible. Vorbisgain analyses both overall level 
and peaks, so after using it, the music sounded a lot better.

I guess the kind of music played will determine whether it is 
noticeable, and thereby vorbisgain's usefulness. Only YOUR ears can tell.
