Music, it establishes setting; creates atmosphere; it calls attention to elements; reinforces or foreshadows narrative developments; gives meaning to a character’s actions or translates their thoughts and creates emotion. Thus the three songs!
1. Passenger | Vincent (Cover)
Again it’s about the Great Vincent Van Gogh. There are a lot of versions of the same song, I love the one by Passenger- A great person whom I had expected to be more famous than his friend Ed Shereen! (Of course, listen to the lyrics!)
2. Beatles | Let It Be 
One of the very few songs that make me feel that I was born in the wrong generation! And I had met a person in Nongriat who could sing the song in a way which is way better than any of the cover songs available on youtube! The reason why the song was special.
3. Louis Armstrong | What a wonderful world ( 1967 )
Its hard to miss this rich, gravelly voice- the man who had strived hard to become one of the most importantpeople in the history of music. There is no particular reason- If its a happy mood, then its Louis Armstrong!
