Interwoven threads. Or just a tangled mess?

This is a fundamental question, one that long predates this blog, and it is a multipartite one. Each is a simple question, at least in isolation and on the face of it, that I have asked myself but as a whole the answer certainly is not remotely clear to me...

Here are some of the questions:

Why do I like music?
Why do I like the music I do, but not that which I don't?
Why has my taste in music changed, particular in the medium - long term?
How are these things related, if indeed they are, in any logical sociological, psychological or even physiological way?

They are not easy to answer, although I would like to try and do so and happily share my answers. Now ask those, and many other such related questions, in combinations and permutations, and the whole thing suddenly becomes almost infinitely complex.

My first comment is blindingly obvious; that I do not know the answer.
That actually matters more for perhaps we are not supposed to know the answer as, regardless of all the huge progress that has been made on our collective science and psychological understanding of the human brain that which we now know, or think we do, still does not register on the scale of that which there is to know.

Two albums, one evening, and I just don't see a problem with it.

Who is to say that I should not listen to bombastic Canadian pyschedelic rock and then immediately follow it with an album of lo-fi acoustic melancholia, if that is what I wish to do?
