Something else to check;
Assuming all the songs are in playlists, and you're using 2.0 of the software, check to make sure that the playlists are not designated as "ignore as child". The ignore as child is a useful for things like audiobooks. It will prevent playlists marked as such from loading unless specifically selected.
In emplode, right click on the playlist, select properties, select the 'playlist' tab. Make sure "Ignore as child" is not checked.

If you want to upgrade the software (lots of really cool new features), the link is at the top of the page "Latest S/W: 2.0-b11"
Auto volume adjust is a feature integrated in Hijack. The link for Hijack is also at the top of the BBS window. Download only the latest pre-built kernal and install it. (for Windows use Tony's Empeg Logo Editor to install). Note you must be using the version 2.0 software to use the kernal.

The auto volume is sometimes nice, but occasionally can make a song sound odd. Try it and see.
