What genre of music is bad music?

No genre is inherently bad,
but it is usually the best music that survives long after the fads have died out.

There is no genre that's completely bad - But whoever said "There is no bad music" is completely wrong.

Modern country

Hip hop and rap

Kpop

Dubstep...

Jazz. It's not bad, I'm just not into it.
