I've found a site where are the tracks of the soundtrack, before WipEout Fusion released:

check out http://gamesweb.com/konsolen/news/de...?item_id=21076
and you will find "Mint Royale Take It Easy (Plump DJs remix)"

Is there an other version of the game in an other country with another soundtrack or is this soundtrack simple a soundtrack of an older version of WipEout Fusion?
