The main circuit theme follows in the footsteps of the "Mario Circuit" theme from Super Mario Kart by firing up the player for the hours of racing fun (and/or frustration!) with an upbeat, energetic tune.
The smooth, laid-back Sherbet Land is just perfect for an ice track.
Double Dash!! has one of the Mario Kart series' most popular Rainbow Road music tracks, which includes a Musical Nod to the Super Mario Kart version in the introduction and to the Mario Kart 64 version in the second half. This version was awesome enough to get into Brawl without being remixed at all.
And then someone thought up some lyrics for it and created this hilarious gem, which could possibly be the entire reason this Rainbow Road theme is so popular.
Appropriately for one of the more chaotic games in the series, the main circuit theme (heard in Mario, Luigi, and Yoshi Circuits) is one of the series' most energetic music tracks.
The boisterous music for Balloon Battle fits the anything-goes mayhem of multiplayer battle modes perfectly.
Baby Park creates an appropriately fairground-like atmosphere for course it accompanies.
Mario Kart DS keeps the trend of awesome Rainbow Road music going with yet another piece of music that conveys a real sense of achievement at having made it to this, the last track in the game. (It's also longer than it might first seem; the main tune actually plays twice before wrapping around, but with subtle differences the second time.)
The game's remix of GBA Sky Garden gives new life to the ethereal Super Circuit track.
GCN Luigi Circuit brings back the lively and just plain fun "main race theme" from Double Dash!!
Luigi's Mansion has an appropriately spooky theme for a track through the haunted house.
The music for Tick Tock Clock opens by imitating a ticking clock before sliding into an almost urgent music track for a journey through the gears of a clock.
Airship Fortress follows the Mario games' long tradition of awesome music for airship levels.
Bowser's Castle has an appropriately sinister atmosphere for the obligatory journey through the twists and traps of the title castle.
Waluigi Pinball dials up the excitement and energy for a wild journey up and down a pinball table. The song is surprisingly catchy and well made, and it's very chaotic and unpredictable, like Waluigi himself. The icing on the cake: the sound effects on the Waluigi Pinball track (item box roulette, Lakitu displaying the lap number cards, passing another driver or taking the lead, etc.) are rendered in mock 8-bit sound.
The Brawl remix is completely awesome. It even takes sounds from the original song.
The fiddle-led music for DK Pass is surprisingly easy-going for the chaos that so often occurs on snow courses.
The Rainbow Road music delivers both the sheer awesome and the sense of finality again, this time complete with a Musical Nod to both the Mario Kart DS Rainbow Road music and the Good Egg Galaxy stage music from Super Mario Galaxy.
The first course, Luigi Circuit, is the first of several tracks to use the game's very catchy "main circuit" theme.
As frustrating as weaving through traffic on MoonviewHighway often proves, it has some of the best music in the game, complete with a variable mix for when you're driving through the city. For added awesome, try listening to both versions combined.
There's yet another deliciously sinister-sounding track for Bowser's Castle, complete with Musical Nod to the castle theme from Super Mario Bros. at the very beginning. It has the brutality and maliciousness of the other Bowser themes, but it seems to also display feelings of sadness and anger, representing a not usually seen side of Bowser: the lonely side.
Thwomp Desert has just the right balance of mystery and energy for a desert-based battle track.
Galaxy Colosseum tilts the scale more toward the mystery side, as befits a space-based battle course.
