Rookie band CNBLUE seemed quite offended by the plagiarism allegations made earlier this month, but the band Ynot isn't backing down so easily. Last week, similarities between Ynot's Blue Bird and CNBLUE's I'm a Loner were drawn, gathering much attention. Ynot has officially announced that they will take action against I'm a Loner's composer & songwriter Kim Do Hoon and Lee Sang Ho. Ju Mong, the vocal of Ynot and songwriter of Blue Bird,�released a press statement on behalf of Ynot on February 1st that said,

We shared our thoughts about this situation, yet the composer, songwriter and company representative have not made an excuse or shared a statement. We have received advice from an entertainment business lawyer and will seek help to take legal action. A FNC Music (CNBLUE's company) representative claimed that we were noise marketing to raise our own popularity. We think that, from the plagiarism allegations, FNC Music is the one noise marketing to up their popularity instead. It seems like FNC Music is waiting it out and expecting this controversy to settle down. ... They aren't giving Ynot respect and haven't cared to take action because Ynot is an indie band. On February 1st, Ynot's company asked FNC Music�to apologize for the insulting statements they made, and asked the songwriters to make an official statement toward the similarities between the songs. This controversy is ultimately between me (Ju Mong), the songwriter of Blue Bird,�and Kim Do Hoon and Lee Sang Ho, the composer and songwriter of I'm a Loner, and shouldn't involve Ynot and CNBLUE.

Biases aside, do you think this has to do with noise marketing or is this a legitimate plagiarism issue?
