I was like you all once.
I was all angsty and hung up on the whole noise and avant-garde aspect of SY and wished their final couple of records harkened back to the "glory days".
Then when I was about 30 I gave up on pigeonholing bands into one type of sound and acceptted the fact that groups mature and evolve. No one living lives forever in their screaming 20's unless you're stuck in neutral mentally and emotionally.
In other words, grow up and learn to accept things as they are. Find beauty in the present and stop trying to rearrange reality to fit your pre-conceived notions.
