It doesnt have to be super innovative... But when its so predictable, im technically listening to the same song over and over. Im asking for some variation.
Its not best to leave it alone, id prefer bands mess around with it.
Many Death Metal bands avoid writing conventional verse-chorus songs. I could name so many good Death Metal bands that do something. Then there is a whole fucking genre dedicated to avoid conventional structure, Progressive Metal and Progressive Rock,, then there is Post Rock, also quite anti conventional then there is Jazz music, particularly Free Jazz, particularly Free Jazz, improvisation based, quite a few Black Metal bands avoid conventionality within their structure too, oh and i forgot mention Classical Music.
It seems like there are many capable musicians, and genres dedicated to breaking conventional song-writing, or atleast innovating a little bit, there are musicians from every genre who innovate.
But the biggest problem with slipknot, is they innovated NOTHING, and get praise for it!?!?!
