It is the same in religion. Some stick to certain beliefs and do not wish to evolve beyond. So it is possible that the lover of music may be tempted to keep to a certain sort of music and will not rise further. The true way of progressing through music is to evolve freely, to go forward, not caring what others think, and in this way, together with one's development in music, to harmonize the life of one's soul, one's surroundings and one's affairs.
