I'm a bit surprised, given the mention of other Dreamcast games, that there's no mention of Airforce Delta's soundtrack:
https://www.youtube.com/watch?v=rR7C-9laJbs&list=PLbPd0JMiEH...AFD's soundtrack is interesting because it tends to be superficially EDM-ish but still pulls in that jungle influence. Track 2 on that playlist is a perfect example: you have a very standard drum beat front and center, but you also have a heavily-chopped drum beat as texture from the very first moment. The resulting syncopated effect with the piano and synth cords is a nice touch (especially in that bit around the 2 minute mark, which itself is a nice introduction to a broader motif throughout the rest of the soundtrack, particularly the finale Track 24 - which itself is another great example of that "EDM main beat with jungle-like chopping as texture" style).
Occasionally that style flips around, though. Track 15 is a good example, where it's the chopped beat (albeit not severely) that takes front and center, yet again producing neat syncopated effects with the synth chords now in the more rigid role. Similar deal with Tracks 8, 10, and 13, though most of these are less afraid to move the chords into the off-beats.
And then there's my second-favorite track, Track 11, which deemphasizes the chopped drums a bit but instead chops up the synth arpeggios for the same effect of adding that nice bit of texture to the pulsing beat and soaring synths.
My favorite track, Track 7, alternates between a very pure-jungle sound across the board (with the drums and chords being heavily chopped and syncopated, often in support of nice long notes) and brief moments of that EDM-like pulse, to great effect.
And of course there's plenty of great stuff outside of that EDM/jungle hybrid, like Track 23's Harold-Faltermeyer-esque "Top Gun Anthem" knockoff, or the smooth-jazz-ish segues like Track 22.
All in all, a fantastic body of work that defined my childhood.

Another game conspicuously missing from the discussion is Buck Bumble and its jungle-to-the-max soundtrack: https://www.youtube.com/watch?v=Lax-KRVVPfo&list=PLeXmIIlkcO...
