I do like screaming, and the growling I hear in my music differs from american, but in Japan its not really like hardcore its more about having fun, or maybe that is just my view of it. I think there needs to be a balance though.
this song has the harsh parts and suttle parts, and they do some rap/hip-hop sounding stuff too. I also love this cuz Aoi screams/yells. I know he likes some american bands and I wonder if thats why he wanted to scream.
I like this song to. I love when they all head bang, I think its called the dirty whine, but your neck hurts a lot after doing it several times.
