Diddy Kong Racing Music Question

I heard some Music on the "Diddy Kong Racing (Extended)" Section of the GH that I didn’t recognize. The Music I’m confused about is:

04 – intro.mp3

05 – entranced.mp3

…Is this Music from Diddy Kong Racing (N64) or Diddy Kong Racing DS?

By the way, the GH Skipped a few Tracks in Diddy Kong Racing:

Treasure Caves (Area: Sherbet Island | Track: 4)

Snowball Valley (Area: Snowflake Mountain | Track: 3)

Smokey Castle (Area: Dragon Forest | Track: 4)

Future Fun Land Theme (Area: Furture Fun Land Lobby | Track: N/A)

Spacedust Alley (Area: Future Fun Land | Track: 1)

…Did the Music from these Race Tracks play in another Race Track that is already listed? If so, which ones?
