Ed the Sock left MuchMusic a number of years ago.
Ever since he left, the channel went from 90% music and 10% other stuff. Now it is pretty much the other way around.
Also, they have no outlet for metal music at all, as LOUD, their metal oriented show, is gone. They also got rid of The Punk Show (although most of what they played there sounded more like indie rock than punk to me; that being said, a lot of the bands they played were bands I am not overly familiar with, so I wouldn't doubt some of those bands were punk at another point of their career).
I remember growing up I would regularly tape LOUD, it turned me on to many of the bands I'm into now.
When Ed the Sock left MuchMusic, it marked the worst day in the channel's history by far.
