automatically guess they are not very? bright. do a lot of people make this judgement? you can hear the music loudly even though it is through headphones. i figure anyone that would pump that stuff into their head must not be that smart. its mindless

well if that's what they like then why should u care. It's not going in your head.

that is so stupid for you to think that just because of a type of music people listen to dont mean there stupid everyone has a type of music that they like and no i know noone that has ever made this judgement

Techno, house and trance music is simply better heard when loud, it's supposed to be listened loud
And no, it's not exactly mindless, depends on your state of mind and you may actually like it quite a lot.
