Green Hill Zone (Unused Mix) - Sonic the Hedgehog

"Green Hill Zone (Unused Mix) - Sonic the Hedgehog" is a high quality rip of the unused mix of "Green Hill Zone" from Sonic the Hedgehog.

Joke
At about the 0:13 mark, the rip turns into a Green de la Bean segment, specifically a bass-boosted mashup of "Green Hill Zone" and "U Guessed It" by OG Maco.
