Because different people enjoy different music.
Some people hate music because they don't understand what the concept of what music is.
People are not nice, so I hate them. People are not interesting, so I hate them. Music is boring, so I hate it. TV programming sucks, so I hate it. Games are not fun, so I hate them. I am not intelligent enough, so I hate me. The world is hard, so I hate it. In short, this is why I hate everything.

people hate it because it is usually hard, time-consuming, and boring but not everybody hates it.

Music preference is a personal matter. Some people hate a particular singer because the music is not their particular preference. Since every one has a different style, an individual singer can be despised by certain consumers. Not everyone loves the same things, and so it is with Justin Bieber or anyone else.
Not sarcasm btw
Balloons hate pop music.
I doubt there are any hard numbers, but probably not many people have a strong enough opinion to justify the use of the word "hate".
