To me, this song starts off with the narrator feeling like there's a hell in life, but no real heaven after a girl broke up with him. (Hell is below him, and then he suggests all that exists above is stars, and no heaven'). The end of the song where it comes in with the backup vocals and the change of the instrumental suggests that even though he won't find this 'heaven', he has found that there are still good things to be found (The stars that are shining on him).
