I'd still ask for the actual Japanese single version that has the Instrumental in as well. Also I'd swear the files there are converted from iTunes? The other day I checked that same page and the English version was not there, so... *shrug*
EDIT: So indeed what I talked about exists... as of November 14th:
01 Fighting Gold
02 Fighting Gold English Ver.
03 Fighting Gold Original (Instrumental)

Guess it will be time to ask again at that time.
