All art is subjective. But there are certain types of art that are less accessible--you either need to have an uncommon taste, or you need to have a deep knowledge of the type of art to appreciate it.

I felt the same way when I first heard jazz bop. Just sounded like noise. Then I played in a jazz band for three years, and by the end of that time, I had a much stronger appreciation for that music. Not because the music was different, but because I could hear more in it than I could years before.

Angine de Poitrine is kinda similar. Some people love it right away, but most of us hear it and it sounds like random noise. But there's a reason they've become popular, and once you get into it a bit more, you can hear some of the cool stuff they do.

For the record, I don't listen to AdP much, but I've been doing music long enough to have an ear to appreciate them.

If you want more info, Charles Cornell does a great breakdown of their music and suggests why people like them so much. Worth a watch.
