Ok I did not expect the combination of Lanky Kong + minor chord lmao. But no lyrics about the handstand and being a balloon?
Shroom Ridge's a great Mario Kart DS song (better than that Pinball/Stadium one imo) and it's why I want Shroom Ridge to return in the next Mario Kart just for this song. I hope they just don't botch the songs like Mario Party Superstars liked doing for too much of their songs.
You also race a car in Mario Kart DS Mission Mode. You can't do this in any other Mario Kart game.
I feel like I should note that Mario Kart and Party have two completely different sets of people working on the music. Mario Party has people from outside Nintendo, usually from T's Music for the newer games, while Mario Kart games (with the exception of Super Circuit and the Arcade games) have music by the big name Nintendo composers, the sort of people you'd expect to see on a main series Mario, Zelda or Animal Crossing title (yes there is a large overlap between composers for these four series).
Taking the most recent game (8) as an example, here are some other games that each of the composers worked on:
Kenta Nagata (also worked on 64, Double Dash!!, 7): Animal Crossing (N64/GCN), The Legend of Zelda: The Wind Waker, New Super Mario Bros. Wii
Shiho Fujii: Animal Crossing: City Folk, The Legend of Zelda: Skyward Sword, Super Mario Odyssey
Atsuko Asahi: Animal Crossing: New Leaf, The Legend of Zelda: The Wind Waker HD, Super Mario Maker 2
Ryo Nagamatsu (also worked on Wii): Super Mario Galaxy 2, The Legend of Zelda: Link's Awakening (Switch),
Yasuaki Iwata: Super Mario 3D World, The Legend of Zelda: Breath of the Wild, Animal Crossing: New Horizons
I noted some exceptions earlier. Which was the arcade games and Super Circuit, the former are games developed by NAMCO and have NAMCO composers on them. Super Circuit is a similar case, where it was developed by Intelligent Systems, and credits people from Intelligent systems for "sound", well that's two of the people (Kenichi Nishimaki & Masanobu Matsunaga), the other one (Minako Hamano), and the Sound Supervisor (Kenji Yamamoto), are better known for their work on the Metroid series.
tl;dr: unless the game where Shroom Ridge reappears isn't developed by Nintendo, you'll have a good chance that the music will be up to the series standards.
Also yes, I agree, Shroom Ridge is my favourite Mario Kart DS song. I like the disc scratch sounds that used here, and a couple other places in the soundtrack. Also I was playing Mario Party Superstars like, an hour ago, and my first thought upon starting Yoshi's Tropical Island was that I wasn't enjoying the music nearly as much as the original, so I will agree there as well. If I had to try and pinpoint it, I feel like it was moved down a key? Or something like that at least, it makes it feel a lot less upbeat. Also I feel the switch to more realistic sounding instruments removes some of the bounciness from original. They both combine to make it feel a lot less fun then the original, and I really like fun in my music.
I guess that technically counts as what I'm listening to right now: banger alert
I still don't trust Mario Kart 8 developers to deliver on faithful music or even better music. I disliked Mario Kart 8's renditions of the Double Dash circuits nor do I like quite as much what they did to Ribbon Road (where's the xylophones) or Toad's Turnpike, though Cheese Land, I liked that, same with Super Circuit circuit and Moo Moo Meadows and Royal Raceway.
Mario Party Superstars DID trot out better renditions. They added a chorus to one of Mario Party 4's ravine-crossing minigame, which really adds to the tension, so I'm not always disappointed with the new soundtrack.
I like Mario Party 5's "style" and instrumentation that sets it apart from the Mario Parties. Speaking of boards, I think I like the space one the most out of the board music?
But you can also recognize Mario Party 4's style too, which also sets it apart. This one is catchy though also brings back memories of giant idiots slipping on bananas and that stupid cabana getting destroyed.
