Couldn't you answer this question with literally any genre?

Not enough people enjoy free jazz and can't wrap their heads around it unless they see it performed live.

Pipes and drums

I have no sex song.

I love grindcore and powerviolence but some people don't.

Some people are just wrong.

"Some won't get it. That's why there are others. God wants it that way."

"Obviously. my audience knows something the others don't."

-Frank Zappa

I also enjoy both power violence and grindcore....as well as noisecore, power electronics, death industrial, and harsh noise.

Some people are just weak.

I love lolicore. Some people have no lol

It took me a lot of tries to get into both of these genres, but once you're in, there's no going back.

Nobody seems to really be into Zeuhl. (Well, apart from Frown and Paul.).
Which is a shame because it's an awesome and all around epic genre.

Huh, 75% people listening music which is promoted on TV and radio, 20% also knows rock, jazz, rap, classic and edm. All other genres and subgenres known and are listened by small group of people.
