I don't get 'physically ill' just from how bad a form of entertainment is, but some do make me cringe and feel very sad.
Like this one

I know, it sounds fine for the first 40 seconds, just skip to 1:00.
Also songs like this are not allowed to be almost 5 mins long, they just aren't.

Edit2:
Samus Aran but a man said:
Dubstep irritates me. It's just not my cup of tea
I know that feel, but I have found one dubstep remix that I actually find quite nice, give it a shot.

Theres a decent chance you still won't like it, just thought I'd put it out that this is the only dubstep song so far that I actually do like.
(If you're turned off by the start, at least give it 45 seconds, then you can say you gave it a fair shake

)
