Now, as to the reason why music is generally forbidden, I can not offer much in the way of logic. I must start with the fact that Allah is the Most Wise, and while we may not be able to understand all that is encompassed in that Wisdom, we are not exempt from obeying Allah and His Messenger because something is not understood by our limited mind. Having said this, I can show that there are effects upon us when we listen to Music. For this, I will simply copy at the end of this class, a research article which discusses this. Even a child is naturally moved to sway at hearing musical tones.
Music is a kind of therapy and as a kind of control over minds.
Last but not least, we have to recognize that Allah, at times gives us commands which we are simply to obey. They may never be explained. This verse refers to the change of the Qibla. There is no logical reason for the change. Allah so much as tells us that it is not the direction that counts.
