Well this page has shown 17 tracks since as far back as March 2010, which is the oldest snapshot on archive.org:

The feed shows that the track listing wasn't edited until May 08, 2011 by WildmanCAL, who gave the tracks the current titles that we have now (here's a snapshot shortly after):

But the feed only goes as far back as September 2009. I don't know if the feed shows the complete edit history for old posts or not.
The 16-track version might be lying and actually contain 17 tracks. The listing since 2010 is accurate for my CD, but maybe it is for the Electronics Boutique one too.
I'm new to VGMdb, so I don't know what you guys typically do in this situation.
