The music board on 4chan. Most of the music discussed on /mu/ is avant garde-experimental-noise-indie bullshit that nobody's heard about. /mu/ users (often called /mu/tants) will flame anybody who likes anything else. Although there is a modest community of metalheads on /mu/ they are generally disliked by the obscure taste flaunting majority that inhabits the board. Basically, it is a big contest to see who listens to the most obscure bands. The less people have heard of the music you listen to, the better.
I went to /mu/ the other day. Never before have I seen so many pretentious tight-wads in a single board.

"Mu" is the correct answer to the classic trick question "Have you stopped beating your wife yet?". Assuming that you have no wife or you have never beaten your wife, the answer "yes" is wrong because it implies that you used to beat your wife and then stopped, but "no" is worse because it suggests that you have one and are still beating her. According to various Discordians and Douglas Hofstadter the correct answer is usually "mu", a Japanese word alleged to mean "Your question cannot be answered because it depends on incorrect assumptions".

Hackers tend to be sensitive to logical inadequacies in language, and many have adopted this suggestion with enthusiasm. The word "mu" is actually from Chinese, meaning "nothing"; it is used in mainstream Japanese in that sense, but native speakers do not recognise the Discordian question-denying use.


Thanks to Thrakem for the source of this definition.

/mu/ is a music imageboard on 4chan consisting of nothing but heated discussions about metal albums that no-one has heard, rap-hatred, Tom Waits-love, and liberal spamming of Dragonforce or Neutral Milk Hotel songs/album covers/information.

The aim of the board is to prove to others that you have a more obscure taste in music than anyone else. The one who has the most pretentious/obscure taste wins, but no one ever wins. Also posting Insane Clown Posse is an instant fail.

It is also the most pretentious thing since Dragonforce.

Anime_Expert.jpg also originated from /mu/. Whenever someone talks about Japanese music, he appears. Though, the picture is so damn exploitable, it's been modified many times over, and is mainly used when someone makes a statement that is stereotypical of fans of the genre/band. This post is then copied, then posted with the corresponding expert.
Your favorite band sucks. If you've forgotten, /mu/ is happy to remind you. Made exclusively for discussing trv kvlt Black Metal, Daft Punk, and Dragonforce
