Road to Cerulean City: Leaving Mt. Moon (OST Version) - Pokémon Red & Blue

"Road to Cerulean City: Leaving Mt. Moon (OST Version) - Pokémon Red & Blue" is a high quality rip of the OST version of "Road to Cerulean City: Leaving Mt. Moon" from Pokémon Red & Blue.

Joke
There is reverb progressively added to the advertised track over time.

Seeing that the song name includes "Leaving Mt. Moon", the music echoes as if it were played from within the cave of Mt. Moon.

This rip could also possibly be a reference to the addition of reverb to the official OST CDs for the games.
