Welcome to Crocodile Isle A spooky and threatening track that plays in the awesome Donkey Kong Country 2 as you enter the Kremlings island to rescue Donkey Kong.
And the GB version of the above from Donkey Kong Land 2. Not quite subtle, but still pretty epic.
Stickerbrush Symphony, a trance-like soothing techno track that is often voted one of the best video game songs of all time.
Of course, if you hate the Stickerbrush levels with a passion that borders on sociopathic obsession, then Stickerbrush Symphony is enough to send you into fits of rage at the memories of dying over 30 times. Others may find the music being the only thing keeping them from breaking their controllers and TVs on those stages due to how calm, mellow, and soothing the track is due to it playing on such difficult types of stages.
Sadly, "Disco Train" is pretty much always drowned out in-game by the fireworks and rail screech effects in the levels where it's played, to the point that the kick-assery of the tune can only be appreciated via the OST.
The Boss theme from Donkey Kong Country 2 (Boss Bossonova) is damn epic, and really suits the mood when you've got things like lightning in the background of the boss battle. Listen to it here
Forest Interlude. Add in the wailing Ghost Ropes and you got a sad & epic song.
Say what you will about the DKC 3 GBA soundtrack, but its versions of Water World and Stilt Village (the former of which is an Aquatic Ambiance remix) are both splendid.
Its versions of Mill Fever and Cascade Capers also equal, if not surpass, their SNES equivalents.
The Game Boy Gaiden Series, Donkey Kong Land, has some gorgeously good music to itself as well. Kremlantis from the first DKL game is a terrific track even in cheesy GB 8-bit.
Big Ape City has one of the catchiest 8-bit basslines of all time.
Even if Grant Kirkhope composed the music in place of David Wise, Donkey Kong 64 had some phenomenal music, probably some of the best the N64 ever had such as:
Trivia: "Jungle Japes" as a title has by and large supplanted "DK Island Swing" as the title of the song. This version of the music is especially fun due to the song having layers of Banjo-Kazooie awesome.
The Boss Remix belongs to one Army Dillo, who was also the Crystal Caverns boss after some cybernetic enhancement.
Even though Kenji Yamamoto of the Metroid Prime series is the new composer and there are mostly remixes, that doesn't make the music any less awesome. One such theme is Mine Menace/The Rocket-Barrel stages.
What about Tidal Terror? (which is another remix of Northern Hemispheres) You can really hear the influence of Metroid Prime here.
Although each and every mine cart stage contains its own unique cover of "Mine Cart Madness" from the original DKC, "Rickety Rails" is the only one to feature an entirely new arrangement of the piece. And IT. IS.AWESOME.
A remix by Panmandan that fuses both versions of Mill Fever into one extremely chill package. The synth in the GBA version perfectly accentuates the bass of the original.
And another that fuses both version of Treetop Rock. That percussion.
Some guy mixed together "In the Air Tonight" by Phil Collins with some DKC2 tunes, mostly Bayou Boogie (since its drums sound very similar to "In the Air Tonight"). The result is pretty impressive.
