4 kinds of music

There are, I believe, four categories into which all music can be divided, according to one's reaction when the music is over:
1. The kind of music you don't even bother to hear till the end.
2. The kind of music that when it is over, makes us glad it is over.
3. The kind of music that when it is over, makes us replay it in our minds and wish it had not ended quite so soon.
4. The kind of music that when it is over, makes us cry because it leaves the air empty, absolutely hollow like a body whose soul has just abandoned it.
