The first track is always game data, that is true. This data is not meant to be listened as music, but CD players believe it is a “track” nonetheless. Fun fact: when playing this track, some CD players don’t output any sound, and some players output the sound (which is garbage).

Many games decided to put the music into tracks after the first one, which is the case for WipE'out", but some games compressed the music inside game files (as mp3 or equivalent format). Every choice has its pros and cons, for instance having music as tracks allowed us to play it from a CD player but made copy easier, and having compressed files saved lots of space and made harder to copy the music.

The point is, WipE'out" game data was so small that they could afford to waste disc space with unused files, which they might have done eventually.
