Welcome to MB, Danzaburou
That's a very interesting profile of your relationship to music over the years, and congrats on doing such a worthwhile job. It must require a lot of patience and empathy.
I thought I liked quite a wide range of music, but apparently not: I would give a "thumbs down" to the ones you mention, I'm afraid, as I don't care for HipHop, Metal or Classical. Still, as you will discover, on MB there's room - and usually a thread - for every type of music on the planet.
