It's comical how bad the music and music direction in this game is, particularly compared to how good the art is.
To clarify, music is not really necessary, just look at the number of successful VN around without music. There is no point adding music unless its actually going to add something to the VN. But in this case the music is so offensively bad that it is just a huge negative until you can turn the volume to zero. But it still occasionally returns, like a really bad curry the next morning.
