It's not about music being extreme. Actually, you can see that other bands in the list aren't something that is generally considered being extreme. I'd argue that listening to Merzbow as a torture method is far easier than Queen exactly because of lack of structure — I generally listen to Merzbow and such when I'm extremely tired and it just helps to relax and stop thinking.
Anyway, I wouldn't be so sure that loud music for 12 hours is actually more humanistic (hah, humanistic torture — I've got to remember that!) than arbitrary item from your list. After all, Chinese water torture [1] also sounds surprisingly harmless, right?
