Poetry and song were originally one. Before independence with reading literature, poetry was music with rhyme. In the past, poetry was an art that anyone could easily enjoy like music, but it became a literary reading and became more and more distant from the public.
...a little...
The greatest virtue of poetry is its implicitness. musicians would have spent the night trying to write lyrics, implying their own experiences, thoughts and feelings, and choosing the right words. They would have put their true and intimate thoughts and minds in writing while facing themselves. I could read these poems and feel the love and pain, joy and frustration, enlightenment and confusion they felt, and when I closed my eyes, I could hear a beautiful song paired with writing.
