Cover art for Despair lyrics by Yeah Yeah Yeahs

I think this is supposed to be an uplifting song. You acknowledge the despair and regrets you have in life. But also recognize that there's hope in the future.

The sun is just a symbol for light which is like a symbol for hope. In addition it's the same sun for all of us. You just need to look up at it and feel it to get this warm embrace.

I can't fully explain the lines of most yeah yeah yeah songs but this is the general feel I get from the rise in tone of the song and brightness of the music video.
