In Wales there is a tradition of the BARD. The bard, was a kind of troubadour, that would travel the highways from town to village singing songs of great battles, sometimes with the aid of a harp sometimes without.
It was often said that as the bard recited a poem that his voice was so beautiful that the sound was like angels singing. This tradition continues to this day with the Welsh National Eisteddfod, which began due to the South Welsh had sweet voices, and the North Welsh had the gift of poetry.
The song is there, it is for the listener, or reader to hear it.
I think songs and poems should be categorized for easier access.
