Discussions are taking place among internet users regarding LUCY's music collection, with some expressing concerns about potential plagiarism. On a forum, netizens examined a thread showcasing snippets of LUCY's tracks, comparing them to songs by other artists that listeners believe bear strong similarities. LUCY, formed in 2020, has released numerous albums under the Mystic Story label.

Netizens noted that LUCY's "You're Right" has been likened to Yorushika's "Say It" (2017), sparking speculations of plagiarism. Other comparisons made in the thread include LUCY's "Hippo" with Eve's "Last Dance" (2018), "Villain" with Eve's "Outsider" (2019), and "Opening" with the theme song of the anime 'Chrono Crusade.' Additionally, LUCY's "OUTRO" was compared to MapleStory's OST "The Cygnus Garden" (2017).

Moreover, netizens pointed out similarities between LUCY's music video for "Complex" and Eve's "Insomnia," suggesting that the animation narratives align closely.

There is a consensus among netizens acknowledging the striking resemblance between LUCY's work and that of Japanese artists, with some suggesting that LUCY may be intentionally emulating Japanese band styles.

Although many netizens criticize LUCY, particularly regarding the songs "You're Right" and "Hippo," some argue that the similarities do not necessarily constitute plagiarism. They point out that inspiration from subculture often results in overlapping styles, especially in genres influenced by Japanese anime soundtracks.

The comments vary on whether the resemblance amounts to plagiarism, with some suggesting that it might be influenced by the genre rather than direct copying. The discussion reflects a split opinion among netizens, with some asserting strong similarities and others highlighting differences in melodies and structures as indicators against outright plagiarism.
