I had originally made this song to celebrate my 21st birthday in 2018, hence the "21" in the title. I don't remember why the word "marbles" is in the title, though. This song uses waves found in the Pokémon GB and GBC games.

This 2024 edition of this song features the following changes: the percussion volume was lowered just a bit, the kick was altered, the song is tuned lower, and the tempo is a bit slower.
