I associate relatively light pop with Jackson.

In fact, it is quite hard to describe without metaphors. Using metaphors, you can usually say that the music just feels as if someone smashes a heavy hammer against your soul and once the music stops, it pretty much feels like you fall down, as if you were leaning against a wall and someone removed this wall. Music which gives me this hammer -> face-feeling certainly includes, but is not limited to songs by Cryptopsy, Vomitory, Berzerker and to some extent Heaven shall burn and Suicide Silence (examples can be easily found on youtube). If you listen to several songs by these bands, I think my term 'light pop'will certainly become clearer :)

That's all well and good, but you said/implied you dislike MJ's music.

Now you're talking about this hammer --> face -type of music, which should be unrelated to the issue at hand - 'light pop'.

Were you, in fact, not talking about 'light pop' when you said "I strongly dislike this type of music"?

If so, it would seem that you were participating in some other conversation, which would be really weird.
