K-pop is not foreign to plagiarism allegations, and this time 4Minute has come under fire for its "Crazy" comeback.

On Feb. 9, 4Minute unleashed its newest EP and title track by the same name. Soon after, certain observers such as Korean blogger Lineage135 accused "Crazy" of plagiarizing from EDM duo Knife Party's song, "Boss Mode."

"All the world renowned artists have signature sounds that allow fans to identify them easily," wrote Lineage135 according to Koreaboo.

"On that note, when EDM fans state something is plagiarized, it means that the sound wasn't created but stolen. The song 'Crazy' by 4Minute didn't simply steal sounds, but copied the progression of songs, melody and even beats."

Ironically, those who are skeptical over this plagiarism allegation also include Knife Party themselves, as member Rob Swire took to Twitter to address the comparison.

4Minute is only one of many allegations of K-pop acts plagiarizing electronic artists. As noted by Soompi, T-ara's "Sugar Free" was also accused to copying DVBBS & Borgeous's track called "Tsunami."

In January, the table was famously turned when Swedish boy band The Fooo Conspiracy was accused of copying EXO's choreography to "Growl." The former later confirmed EXO's inspiration online, but did not acknowledge the claims.

Such huge inspirations for us as dancers! Loving all your work. #DancingRoleModels ️ https://t.co/heC83JyKLW — Omar Josue (@OmarRudberg) January 9, 2015

Most recently, British singer Robin Thicke and American R&B singer Pharrell was sued by the Marvin Gaye estate for allegedly copying Gaye's 1977 song "Got to Give It Up." According to Time magazine, a jury concluded that Thick and Pharrell did in fact copy the song for their smash hit "Blurred Lines" and $7.3 million will be awarded to the Gaye family.

Reportedly, Thicke and Pharrell plan to appeal the verdict on this landmark case.
