My list concerning remixes as well
1
Destiny (Ablaze)
: I've waited so long for this song since smash 4 not only almost every ablaze theme has made it during the last game but this one in particular was missing, I feel like Sm4sh was really not for me with all sign pointed out about that. But during the first trailer of lucina during june 2018 I recognized immediately the song and I feared getting an another medley but it gives me the feeling "you are gonna love this game". But now not only this song made it but it is a remix done by ACE it seems (I saw a comment of someone mention that on youtube) with a medieval folk vibes in it , it has blown away my expectation. This is maybe not the best remix but I waited so long that finally it was worth it.
2
Big Blue : Not expecting that when I saw there was a remix of Big blue, I was expecting an another rock / metal remix but it was a full electronic one, I feel a bit disappointed at first but after listening over and over again it has becomes one of my favorite remix from the game, the departure of the music with this electronic sound in the background giving a feeling that you are on the track and the race is about to start, full electronic instruments give the feeling of retro F-zero games with some modernity in them , catchy all the way up I want a new f-zero after hearing it.
3
Awake Wut? : This game is not forgotten? Not only this is only the second castlevania games I played (the first was Castlevania 64) but this is a music that was stuck in my head for all the following years, I love that theme when I was young and remixes about it made by fans were not really good (only one was close to the original material). But this? This is really a pleasant surprise and gives justice to this song even more now.
4
Vs. Parasite Queen : I'm not a fan of the metroid franchise and played only two of them without finishing them (metroid prime 3 and other m) but this theme as something that I really love : rhythm. This remix is very repetitive with some chorus at the end but the rhythm is so catchy with an obscur / dark vibes that suits perfectly the character that I felt in love.
5
Nintendo Switch Presentation 2017 Trailer BGM : I can't remember how many time I watched the trailer during the Nintendo switch presentation in 2017 maybe over 100 lol just because this music was from an another world of epicness. I was not sure this remix was gonna be good when I heard it during a gamexplain footage but now I'm sure it fits perfectly smash keeping pace dynamic all the way, maybe some transitions feel a bit strange at first but after listening many times it doesn't bother.
6
Crocodile Cacophany : Rights to the feels , brings back nostalgia , it's like the original song made with real instruments without trying to do so much more in a risk to denature it. it's really the perfect remix of it.
7
F-ZERO Medley : Burning Ranger, Daytona, this japanese singer has really a unique voice so doing a song about F-zero this is how you can show some respect for this franchise, the pace is good and this medley has a really good transition between all f-zero songs , I'm a bit disapointed that the singer who can sing at a higher pitch stay almost safe during the whole song (even though the back are really high). Likewise bigblue I want now a new f-zero game.
8
Midna's Lament : chills, during the whole song chills. I saw people saying sakurai hates zelda but composers in this game give so much love for the franchise and this remix is just f**** epic, midna is maybe not a character in this game but this song is just wow with this example we can see there are others ways to show franchise or character have importance not only by being new comer or echo or AT or mii outfit. I dunno why this song is not higher in my list but clearly this was an amazing surprise.
9
Fortress Boss - Super Mario Bros. 3 : Very catchy and melodious during almost of it that will suit perfeclty smash and using the mushroom sound is really a smart choice to bring something unique to the remix , but why almost ? Because during a little more than the middle of it the composer choose to bring Ice land one of the most creepiest song I heard during my life (it was not a coincidence that they choose it for the creepiest mini games for mario party 1) and it gives you the feeling that something was really wrong to choose a music like this for the wolrd 6 of Super mario bros 3 , thanks to this composer now we know we are not alone to think that.
10
King Bowser - Super Mario Bros. 3: Koji Kondo has gone really wild on this one, not only it shows that bowser is really a vicious deadly boss but this is the darkest remix of all of them imo , brooding atmosphere and crackling electric guitars all over the place. My only little complain it's a bit repetitive but this is not Koji Kondo's fault.
To be honest all remixes are really good in this one so it's really hard to make a top ten, I think they are my favorite remixes of all smash games since brawl (SM4SH was really very disappointing music wise ).
