The song is from the Game Boy game "Kirby's Dream Land". I just recorded it from my Game Boy Color via the earphone jack through my Behringer UCA222 and slapped this old meme video onto it. No artificial looping or modifications or enhancements to the audio was done, except from fade out and amplification.
