This is a song for sad and quieter moments on modern television. This music is usually used after a dramatic moment, and the show cuts to a new scene with no dialogue or even ambient sound. The music is not overly depressing, but leaves a sense of a journey, a bit of emptiness that helps move the plot along and continue the story.
Music like this is frequently used by charities and non-profits to convey their need for support, to help further a cause and call to action. You can envision this as helping to raise support for hunger, support for animal rights, for human rights and political causes.
