The audio is terribly loud, and many tracks have a noticeable click when the track repeats. But these things were easy to fix.
However , many of these tracks are ripped improperly. Many of them were apparently saved on the disc in separate files, and instead of piecing them together, each file is saved as its own track and loops individually, including short two-second intros that now just loop several times and fade out.
Very poorly done.
