In addition to its own music, the Super Smash Bros. series has a habit of taking older music tracks and making them awesome, whether they already were or not. The entirety of Brawl's soundtrack alone could count considering it featured the largest number of videogame composers to work together on a single game.
Note: If the music is unchanged from its original game, then put it in its relevant section of Crowning Music of Awesome, not here.
Original
The target test track from Melee. Watch the comments on pretty much any Youtube video with that song. You get at least ten people complaining about how that song isn't in Brawl. Considering how awesome it sounds, that's understandable.
The original game's theme was reworked into Final Destination for Melee.
Go K.K. Rider! is high on many a player's favorites list.
The 2:00 AM remix in Brawl is a neat rock/pop remake of what was originally a very low-key, mellow jazzy piece.
Even if not very fit for fighting, the double remix of Tom Nook's Store and Town Hall is so catchy enough to make you come back to listening it. And if you don't, you're gonna whistle it on forever.
The Roost/Brewster's Roost is a beatiful arrangement of the original which sounds like from a romantic movie.
Title (Animal Crossing: Wild World) rains gentle chills of nostalgia down to your spine, reminding you of those times of playing Animal Crossing on DS so addictively. Sucha cheerful tune.
And for more dedicated Animal Crossing-players, the composers hid in some recognisable tunes from the series in the tune:
Blather's Museum-Theme can be heard (topped with clock sounds)
There are throwbacks to 3pm-4pm's and 6am-7am's-tunes (which would play each corresponding to the real-life clock in your DS.)
And most of all, the Loan Paid Off-jingle is also included, just for the hard workers who spend their months (or maybe days) paying their loan for Nook in order to get a bigger house. How dedicated!
Skyworld is also very majestic and adventurous rendition of the Overworld/World 2-theme from Kid Icarus, reimagining about the heroic sidescroller part on land after the painful beginning that is Underworld.
Have you noticed that in that theme they used electronic accordion and bongos to emulate the feel of the NES soundbits from Kirby's Adventure tracks anyway? Try to listen for this for an example. You need to have very good ears for to hear the bongos similar to the remix, though.
It's the Title Theme from the first Kirby game!!! They didn't forget about Kirby's Dreamland after all!!
Every hardcore Kirby-fans will easily love Boss Theme Medley, which takes all the best tunes throughout Kirby's history of battles and throws it into awesome medley fest. Particularly the first four (Adventure, Dreamland 2, Super Star and Kirby 64) is sure to give goosebumps of Kirby-gaming nostalgia.
The incredibly calm and peaceful All-Star Rest Area from Melee, which is originally from Super Star, which is itself based off Float Islands from Kirby's Dream Land.
Tal Tal Heights, which is actually a mix of the Link's Awakening overworld and the actual theme of the same name, is possibly the best of the many overworld Zelda remixes.
Ocarina of Time Medley, a mix of the six main tunes Link can play on his Ocarina, is pure nostaliga for Ocarina of Time in song form. Melee also had Saria's Song by itself, which unfortunately wasn't retained for Brawl.
Song of Storms. An amazingly epic remix of Windmill, Ganondorf's Theme, and the Serenade of Water. If anything, the first 3-4 seconds of the song, that INTRO, should tell you the epic you're in for.
Vs Ridley is nothing short of raw, unmitigated badassery in musical form.
The remastering of the original Metroid's ending theme. Especially epic because it plays when you beat the final boss in Classic or Boss Battle mode as Samus. Delicious chills shooting straight into your soul, man.
Melee's version of Brinstar Depths is just amazing. Especially when the melody hits the second repeat and the drum track kicks in.
What about the theme for the Melee level of Onett from Earthbound? The alternate song, "Pollyanna (I Believe In You)", is great. There aren't even any vocals in there, but you want to sing along anyway.
Melee had the theme for Fourside, which is also notable for being the only track that originates from Earthbound/Mother 2, rather than Mother 1 or 3. For some reason, this theme not only didn't return for Brawl, but a handful of Earthbound tunes were considered for Brawl but not put in!
At least the second half of Earthbound's Eight Melodies has endured as Ness's victory fanfare - oh, wait, no, he and Lucas share a victory theme taken from Mother 1 in Brawl. More of a Wall Banger when you realize that Meta Knight has his own unique variation of the Kirby victory theme play when he wins.
Humoresque of a Little Dog, AKA the shop theme. A little out-of-place for a heated free-for-all, but awesome nonetheless.
The best wild Pokémon battle themes of the series, those of Sinnoh and Johto, both recieved insanely EPIC remixes in Brawl and Melee respectively. Both are in Brawl.
's Wild Pokémon battle music is actually a medley of the following Generation II tracks: Wild Pokémon battle theme, Gym Leader battle theme, and Champion battle theme.]]
's Wild Pokémon battle music is actually a medley of the following Generation I tracks: Pokémon Trainer battle theme, Gym Leader/Elite 4 battle theme, and Wild Pokémon battle theme.]]
Of course, there's always the most famous video game theme of all time. Koji Kondo himself made this remix of the Super Mario Bros. Ground Theme.
The Underwater Theme, which takes a classic, and gives it two remixes along with the original all in one track!
Title/Ending (Super Mario World) is a tearjerkingly happy overture for ones who owned Super Mario World as their first Mario-game, composed of catchy beginning, and is carried onto bittersweetingly composed fast-tempoed ending theme.
Mario Kart DS has the already kickass Waluigi Pinball. The Brawl remix gives it a techno-speedup overhaul, along with mixing in themes that would later be used in Wario Land: Shake It.
Luigi's Mansion is given a perfectly fitting haunting track for its stage.
For most surprising Mario tune in Brawl we have the Easton Kingdom theme from Super Mario Land.
Main Theme (New Super Mario Bros) is very catchy to listen, and if that wasn't enough, the Stage Clear Theme at the end of the theme makes it more worthwhile for NSMB-players.
Shin Onigashima. Really, if the original song would have qualified (several more are cited below under their original games), it got put into Brawl and made even more awesome.
Lip's Theme of Panel de Pon-fame is very technoish and catchy rendition of the original, with more clapping and beat than ever before.
Is the technoish style of the song maybe a throwback to the soundtracks of the latest Panel De Pon-game back then, Planet Puzzle League?
If you ever wondered how to make Tetris music more awesome, Yoko Shimomura did it with Type A
Ever wonder how a Mariachi remix of Tetris tune might sound? Well, now you know.
There's only one Golden Sun track, but it's possibly one of the most epic battles themes ever.
being medley of title theme (at the beginning), main theme (in two segments, another coming after instruction theme) and the cooking/recipe instructions theme at the middle where the character talks
from a electronic cookbook application for DS, released only in Japan (back then) but you can't help but admit it's also the one of most magical tracks in the game.
The orchestral live album Smashing...Live! is chock full of fantastic arrangements of melodies from Melee. One such piece is the "Smash Bros. Great Medley," especially the Big Blue section.
Remixes
Even the weapons aren't immune. Think the hammer's music is unworthy of a remix? Let me prove you wrong. Bonus points for the hammer pulling a Superman pose.
