That isn't good enough. A tune with a low average to peak ratio will
still sound too quiet. MP3 Gain looks at average to peak ratios and
analyzes the perceived quietest track of a group and then lowers the
other to produce a similar volume.

How does it cope with a group of files including an acoustic ballad
and a hyper-compressed rock song?

Mp3Gain has three ways of adjusting the gain; 1 is called Album Gain, this
will change the average gain of the album to a certain user defined level
(default is 89 db) so some songs will be higher than 89 and some lower but
the average for the album will be about 89 this maintains the relative
volume between songs; 2 is track gain, this will increase or decrease all
songs to a user defined gain, so all songs are at the same volume; 3 is just
adding a constant gain to all songs, no analysis is done.

For the above example, using album gain you can increase the volume of both
songs but the relative volume between songs will remain the same, using
track gain the volume of both songs will be about the same. Setting the
gain too high will cause clipping. MP3Gain will show you which songs will
be clipped prior to applying the adjustment.
