I'll touch on that... Most people don't discuss it because the reasons for liking or disliking a style of music usually would fall under the category of "politically incorrect" and many times could be insulting to certain ethnic or religious groups.
I like ultra heavy dark metal because it's kinda like committing suicide, only without the dying part. (in other words, it helps make life go away for a while)
I like electronic for it's relation to 8-bit music. (8-bit is the grandparent, electronic is the grandchild, and dubsep is the infant lovechild of electronic and every other genre)
I like dubstep for the above reason, and generally like all forms of it if it's done well.
I like certain country music. (not the repeated stupid lyric "blues-like" love songs, the good stuff)
I like blues. (not the jazz that claims to be blues, real blues)
I like certain types of jazz. (not the stuff that claims to be blues, as previously stated)
I like some rap. (not the stuff that's all about making money at the cost of everyone and everything else)
I like the rare few R&B (that's modern blues to the lay people) that isn't trying to be jazz.
I like classical. (can't beat a good Beethoven or Tchaikovski for getting an emotion transmitted through your ears)
I'll listen to classic rock or oldies all day, any day. (grew up with it, even got a decent Bon Jovi concert when my Mom was at 8 months, always makes me feel at home)
I can't stand pop music. (meaningless fluff that only makes 13 year old girls feel anything, and usually because they don't have a brain yet)
Can't stand any of the demonic/witchcraft lyric songs. (even if I can't understand the lyrics, and have no idea, it still makes the hair on the back of my neck stand on end)
No feelings either way about songs that focus on murder or mutilation. (don't ask why, I don't have a clue)
Don't care for songs solely focused on sex, cheating on a significant other, or rape. (just feels like listening to them is too close to doing the deed)
Rather like songs that focus on drug use. (generally the songs were written under the influence, and that tends to improve the mood by a lot)
I like suicide songs. (makes me feel like I'm not alone in wanting it all to end if it won't get better)
I feel like I'm missing some, so feel free to ask about anything else related that you are wondering about.
**DISCLAIMER**
I am not suicidal. It's selfish, and makes your life amount to nothing. Go lose your life in a meaningful way if you're dead-set to do it. (like suicide by saving a bunch of troops in combat, or by assaulting a rapist in-the-act)
