Super Mario Bros. Music - Ground Theme (NES Classic Edition)

"Super Mario Bros. Music - Ground Theme (NES Classic Edition)" is a high quality rip of the NES Classic Edition version of "Ground Theme" from Super Mario Bros.

Joke
This is an arrangement of "Nightmare Night" by WoodenToaster & Mic the Microphone using the advertised track's instruments. At 0:11, the vocals to "Nightmare Night" are mashed up with the track with a bit-crushed filter applied.
