This video deconstructs the Peach Gardens theme from Mario Kart DS in the form of oscilloscopes, notes, and separated sounds to get a better understanding of what is included in this song.
Original track is composed by Shinobu Nagata.

Chapters:
0:00 - Bass and percussion (Actually starts at 2s)
0:51 - Backing melodies and harmonies
1:40 - Lead melodies
2:28 - First buildup
3:17 - Second buildup
4:06 - All Instruments

One of my favorite tracks from MKDS. Also, if you look closely, you can see that all the characters are rocking with the invisible boatmobile. (100% intentional)

I have original tracks too! Most of them are chiptune:
