The data tracks are:
[ul][li]the 3-in-1 menu[/li][li]Gate of Thunder[/li][li]Bonk's Adventure, CD version[/li][li]Bonk's Revenge, CD version[/li][/ul]
I don't know about the order of the data, but it makes sense now, right?
As for that song, it was used on some other CD game, I heard, though I forget which one. Perhaps it was an example Redbook song (like those example pics on some CDs.)
