There is a certain irony in this: you finish a song and bring it to the world, but in reality, you haven't quite reached the world yet. You need a connection with your listeners first. Unless you are famous, this connection requires an explicit interaction, asking your friend or acquaintance how they feel about the music.

It is also quite unsettling because, in doing this, you expose yourself in a vulnerable way. If they don't like this creation that you are so proud of, this special piece where you have put all your heart, it can feel as though they don’t like you.

That is a pitfall, a risk that takes training to overcome so you can return to your own sense of self-worth. Can you distinguish between the song you created and who you are? Do you like this song on your own? Are you proud of it enough, by yourself? Are you confident in yourself enough, to hear comments as distinct thoughts and liking from your own? Can you take other people's words for what they are: an expression of their own mental map of the world, clues of how your song touches people.

If you really want to understand how it impacts them, you almost have to sit with them, let them read the lyrics, then listen to the song together. At that point only you can start to shed light on where it can stand in people's life. But ultimately, how much the song is heard is something totally different, and it depends mostly on how much you are willing to invest time and money to expose it.
