"Ievan Polkka (Beta Mix) - Hatsune Miku: Project DIVA" is a high quality rip of the beta mix of "Ievan Polkka" from Hatsune Miku: Project DIVA.
Jokes[]
The melody has been changed to "Angry Birds Theme" from Angry Birds, with the vocals pitch-shifted accordingly. At 1:04, the "Yeah!" from the advertised track is replaced with bird squawks from Angry Birds. After the track ends, at 2:26, audio of Patrick Star yelling "Finland!" from the SpongeBob SquarePants episode "Frankendoodle" plays, referencing how the advertised track and Rovio Entertainment, the company behind the Angry Birds franchise, are both Finnish.
This rip may also be a reference to guitarist Jay Foreman's live song "Angry Birds", in which he sings about Angry Birds to the melody of "Ievan Polkka".
