Well ... I don't know how much it will help but Sound Forge has a nifty 
normalization feature which works on RMS rather than peak. It's pretty good 
for bringing all the songs you wish to work with into line dynamically.

I only had to deal with four files so it was quite straight forward. I just 
added them all in to the same file, and then normalized them there using 
RMS. This has the advantage of clipping off the loudest sound in your 
loudest file, while still raising the dynamic levels of the quiet parts so 
that, generally, they are all in line with each other. Having done that, I 
then cut the files back up again and I once more had my three originals.

This is fine if you've got half a dozen files or less, but I would hate to 
have to treat 60 like that!! Presumably, one could design some sort of 
batch file that would first examine the levels in each one, present one 
with some options, and then process each one accordingly.

I have, however, found the SF RMS normalization very useful.
