The plagiarism controversy surrounding singer IU's "The Red Shoes" has entered a new phase.

Recently, Noden Entertainment Publishing stated on their official website, "We were surprised by the claim that IU and her agency contacted Nectar regarding the copyright infringement issue. This is not true." They added, "IU and her agency did not contact us nor did they respond to our multiple attempts."

Noden Entertainment Publishing is the official music publisher that released 'Hears Us' through a project with the German band Nectar. 'The Red Shoes,' a song composed by domestic composer Lee Min-soo, was accused of plagiarism in 2013 as it closely resembled Nectar's swing jazz song 'Hears Us.'

At the time, IU's agency, LOEN Entertainment, countered, "The overall melody, composition, and instrumental arrangement are completely different." Renowned composers like Kim Hyung-seok and Bang Si-hyuk also concluded that it was difficult to see 'The Red Shoes' as a plagiarized piece.

On June 21 (Local time), IU's current agency, EDAM Entertainment, refuted, "Regarding the announcement recently posted on Noden Entertainment Publishing's website, our company has confirmed the email received from Noden Entertainment and responded to it."

In addition, they said, "We are also revealing parts of the email that LOEN Entertainment (previous company) had responded through a lawyer in 2013," and released the past emails that LOEN had sent.

As the claims of the two companies conflict, there is growing interest in the industry about where this battle for the truth will lead.

Meanwhile, on May 8th, a citizen identified as 'A' accused IU's "The Red Shoes," "Good Day," "Bbibbi," "Dear Name," "Zezé," and "Celebrity," a total of six songs, of plagiarism and reported her to the police on charges of violating copyright law.

In response, EDAM Entertainment stated, "The accuser is not raising plagiarism suspicions against the composers, but is solely targeting IU," and announced a strong response.
