"Underground BGM (Alternate Mix) - Super Mario Bros. 3" is a high quality rip of the alternate mix of "Underground BGM" from Super Mario Bros. 3.
- This rip marks the first appearance of "Differences™" on the channel, which would later serve as Season 3 meme.
- Coincidentally, the ripper, Big Purp, is the same person who created "Differences™".
- This rip was originally named "Underground - Super Mario Bros. 3".
