There is something nostalgic about listening to music with words spoken behind it. Not rap, but calm music with a good voice reading something. Music has a huge piece to play in our perception and emotions in a situation.
Alan Watts had many speeches in his life, and someone has taken a bunch of those speeches and turned into songs.
I honestly don’t even pay attention to the words actually being said, but the peace that comes from listening to someone talking can be a wonderful thing.
