This song is from the album Undun by the Roots. It is called Lighthouse. The words to the chorus are interesting. Imagine lying in the ocean and seeing a lighthouse nearby and no one sees you because it is unmanned! Imagine the feeling of fear! Think automation? Unmanning lighthouses?
No one’s in the lighthouse
You’re face down in the ocean
And no one’s in the lighthouse
And it seems like you just screamed
It’s no one there to hear the sound
And it may feel like there’s no one there
That cares if you drown
Face down in the ocean
