Soul of nation
We have different genres and kinds of music today and there is almost no difference between those songs and tunes. Most of songs are about love and separation and so on. But, there are songs one can never confuse with others. There are songs of peculiar character and peculiar color and peculiar emotions; those are national songs common for every nation. There were times when people lived so far away from each other and there were no communications between them and those were times when music of every nation was pure of everything foreign. The music of nation was really a soul of nation and all those unique features of music were the reflection of unique features of nation. Things are different now and when you hear a song on the radio or elsewhere you will never guess who the singer is. But, if listen for a national old music people used to have you will never confuse Scottish songs to German songs, for example. So, the music is a soul of nation but not a source of income, at least that is how it was and that is how it should be.
