LEGO Racers (GBC) (GB) (gamerip) (2000)

hey, first of all thanks for the upload!
I have a quesion.
is the source of this album known? Can't find any official source other than ripping from the game itself, but e.g. the main menu theme is only 57 seconds long while in this release its looped until its 2 minutes long, did you make it into this format?

I'm looking for the best possible quality of this soundtrack, so far this upload, and the audio files ripped from the ps1 disc seems to be the best.
