2.12 Differences between releases

Most releases have several versions available.  Special versions, usually 
imports from central Europe or Japan, sometimes contain extra tracks not found 
on the other releases.  Check it out before buying to avoid having to buy
several versions of the same single to get all the songs.  :-) 

For more details, consult the discography:
