13 (There is a Light) is pretty terrific and works well as a closer. I understand those who wanted Love is Bigger to be the finale, but this song has to close if the band wanted it on the album.
I choose to ignore Bono saying the lyric is really "dumb" and not "done" as listed in the liner notes. "Done" works better in my opinion in the song alone and in context with the album. Love is Bigger says "when you think you're done, you've just begun." Why would Bono work against that theme? I thought these two songs were in lockstep based on this lyrical connection.
However, it was funny to hear Edge say he thought the lyric was "dark." Dark and dumb also work, but I feel "done" is the best choice.
