In no particular order (except the first one):
"Torigoth (Day)" - Xenoblade Chronicles 2Perhaps the most vibrant and cheerful Irish tune you'll ever hear. It fits the town of Torigoth perfectly, and can always brighten my day.
"Beautiful One Day" - Rhythm Heaven FeverNintendo didn't need to empower women
this hard, but I'm dazzled that they did. A fantastic song that teaches the value of self-worth and goes crazy on the electric guitar.
"Masters of Darkness" - Pandora's TowerThis is the second boss theme of the game, used in towers 6-10. After naming the six laws of the Aiosian religion (arbor, flamma, terra, aqua, aurum, tenebrae-lux), the booming singers reference a poem by Wilfred Owen,
Dulce et Decorum Est--"it is sweet and fitting to die for one's country." This is a fate that the subjects who were transformed into the Masters of the Thirteen Towers (bosses) were honored to take... but one your character, Aeron, wasn't strong enough to follow. The women's choir kills it here, and they're even more fitting for this piece. Each of the six laws is governed by a god and goddess, and the first five towers contained statues of the gods. It only fits that the next five would be built to goddesses, and have a female choir.
"Fruity Factory" - Donkey Kong Country: Tropical FreezeAn extremely moody piece by the legendary David Wise. A great tune to vibe to whilst platforming across watermelons. I'd call DKCTF the best soundtrack in gaming. Honestly, every song in this game is excellent, so you can't go wrong with any of them.
"Whispy Woods Land" - Kirby's Pinball LandA magnificent tune hidden away inside an overlooked Game Boy game. The second half of the song really seals the deal. This pairs very well with the beeps and boops of a frantic pinball table. The
Kirby's Dream Buffet remix is also excellent.
"Rainbow Across the Skies" - Kirby and the Rainbow CurseA whimsical melody that gets more exciting as it goes. This fits the Kirby series extremely well and is a delight to behold. KatRC has the second-best OST in gaming, so you should check these out, too.
"C-R-O-W-N-E-D" - Kirby's Return to Dream LandWhat else fits the Kirby series extremely well? Intense, crazy villains. This song belongs to a mastermind who has gained limitless power and is only a stone's throw away from reaching and conquering Planet Popstar--at least, his possessed body is. This piece adds to an already brilliant final showdown. The first bit sounds a little like the Nightmare Wizard's theme from
Kirby's Adventure (though upon further inspection, it's original), the midpoint is a reprise of the Lor Starcutter theme from KRtDL, and the finale is pulled from the Crystal Area in
Kirby Super Star. It's a final boss song for the ages!
"LocoRoco Song (Kulche Version)" - LocoRocoThis might be the happiest song I've ever heard. Kulche's childish voice gives it so much life, though Chavez's Argentinian accent is almost as pleasant in his version. Go ahead, babble along to this weird song!
"The Heritors of Arcadia" - Fire Emblem Echoes: Shadows of ValentiaThe cleric, Silque, sings a beautiful song that may be the last words of Mila, the divine Mother of the continent of Valentia. It contains a motif from "What Lies at the End," another intrinsic song in the game, and references the hero, Alm (the jasper lion). It's a sweet, adoring song that makes you feel the tenderness of a mother's love.
"Beware the Forest's Mushrooms" - Super Mario RPG: Legend of the Seven StarsYoko Shimomura did a terrific job of bringing her
Final Fantasy magic to the Mario series. This jaunty track makes the famous Forest Maze one of the game's highlights.
"Title Theme" - Mario & Luigi: Bowser's Inside StoryThe most elegant theme on the DS. It masterfully contrasts with the game's zany tone and fits with the title image: Princess Peach's Castle on the top screen, and a watery reflection of Bowser's Castle on the bottom. Makes you think, or even tear up--I won't judge either way.
"The End" - Drawn to LifeSpeaking of tearing up, this is a beautiful duet between two lovers who are unsure if their relationship can last. It ties in the game's main theme and pairs perfectly with the game's ending. The words, "to a life with you," always makes my eyes misty.
"Main Theme" - Super Smash Bros. BrawlAlright, enough of the waterworks. How about an epic Latin song to accompany your unbalanced, tripping knight?
Brawl's got you covered.
"Skyloft" - The Legend of Zelda: Skyward SwordSkyloft is the coziest floating archipelago you'll ever find. This peaceful song is a big contributing factor there. The laidback tone goes perfectly with the woodwind and brass instruments.
"Temple" - Zelda II: The Adventure of LinkAn ominous, droning tune that bears down on you as you explore the six palaces (temples in the Japanese version, hence the title). I've always thought this made them a little scarier. The
Super Smash Bros. Melee and
A Link Between Worlds remixes are also excellent.
I can post more if you want.
