Here, even the children sing at the end.
And in general, it seems to me that Klov's hearing is tuned to a cacophony. He wants a lot of sounds that fill the entire sound space, so that the entire background is in this music. But if the melody is disjointed, and the instruments are separated from each other, each playing its own melody and each representing something interesting, then he doesn't like it very much.
By the way, that vocalist, whose photo I posted, likes Coldplay and Muse. :)
