It seems that Psy is now so popular that he is being filed for lawsuits against his song.

Last October, someone filed a lawsuit against Psy saying that his song "Gangnam Style" was plagiarizing his song. 

The person that filed the lawsuit stated that out of the 10 melodies of the song, all of them were plagiarized except for around 2-3 parts.

It is stated that if a melody is the same over 4 parts, it is considered plagiarism.

Even someone who did not know anything about music stated that Psy's song and the song that is assumed to be plagiarized from did not have any parts that sounded the same.

It seemed hard to believe that this song was plagiarized.

A music professional also stated that if it were to be plagiarism, then he chords would be the same, but in this case, nothing seemed to match.

The person stated that they made the song in 2009, but it was revealed that Psy released his in July 2012 and this person in November 2012.

Psy is just shocked at the fact that someone had filed a lawsuit against him for a reason such as this.
