I’ve circled
several things. First, note that you will need to be
in the Playback panel. Now. make sure there is a
check in the Sound Check box. This will cause iTunes
to begin analyzing the volumes of your iTunes files.
If you have never had Sound Check selected, this
process can take a quite a while, especially if you
have a large library.
If you would like songs to crossfade (transition
between songs) by lowering the volume of the song
being played while the other begins playing and then
increase its volume to the set level), you will want
to check Crossfade Songs. Be sure to quit Preferences
and try out your crossfade settings.
The Preferences panels for applications frequently
hold some interesting and valuable choices. Be sure
to check them out!
