Exactly! Art lies in the imperfections!
If something's perfect, then yeah it's impressive at first but you don't really notice it after awhile cuz it has no character. If something is imperfect, you notice it at the time and it's hard not to be like "NOPE DO NOT LIKE" because it interrupted your sorta chilled-out "enjoying the music" state, but those imperfections are what you come back for down the road.
Of course some imperfections are going to bother me no matter what, same as anyone, and there are some people who adore "perfect" songs and always will because that's just their taste... but if the Ayu fan community has one thing in common, it's that we're not afraid to get to know things and learn to accept their flaws over time. *nod nod*
