It is fine if you are entitled by your opinion, I think that's great.
Here is the reason why I hate rap and Hip hop (basically Today's Radio music)
Reason #1
Too Repetitive : saying the same words over and over and over and over again is not cool, it practically makes people understand that you are not smart enough to think of other things to say in the song.
Reason #2
Most of them are Racist:
People Hating on other people just because of their race and basically their skin color. Mostly offensive to Caucasian People. Enough said.
Reason #3
A lot of them (Like Lil Wayne) Talk too much about drugs, sex, and being greedy.
It is the truth, go watch some Music videos by people like Lil Wayne or Pitbull and you'll know what I mean.
Those Are my Reasons, I personally prefer something like Christian Rock, Techno, Dubstep, Classical Rock, and Screamo.
Some guys think that all rock is emo, hmmm I didn't know that John Lennon and Paul McCartney were Emo.
