The Meaning of Music.

I was thinking of the songs I would analyse in the future, and I realized that most songs I have in mind are in the genre of Metal, something that many don't enjoy.
I believe that the point of doing this is not just write about the songs I like, but the ones everyone can relate to. As an example, Symphony of Destruction or Where The Rain Grows might have very deep meanings, maybe they're very intelligent or well written. But only a few actually enjoy the music, the feeling of this genre.
Which leads me to the title of this post. I don't think I can disclose the meaning of music, that would be a feat even for the greatest philosophers. But I have to acknowledge that lyrics are not everything, that the rythms and harmonies in each song are just as important. Because, though it might be great lyrics, the words were created with the music, and they should go along. And because they are to be together, one must listen to the music to find the core of meaning that a harmony of this kind conveys.
So I want others to tell me what songs they like.
What songs do you think have a special meaning, or go further than just the surface?
