This is a parody of C.N.Blue's 외톨이야 (I'm a Loner), a hit single that was the source of much controversy. The accusation was that it ripped off the song 파랑새 (Bluebird) but Ynot.
The title of my parody is 내노래야, which menas "It's My Song." You don't have to know what the lyrics in the original mean to understand this, although it helps to be familiar with the song itself.
But the fact of the matter is that plagiarism and musical parasitism is rampant in the Korean music industry. Please share this song with anyone you know (especially if they're Korean) to spread awareness of this problem.
