Perfect Day - Lou Reed.

Somewhere By Barbra Streisand or Could It Be Magic By Barry Manilow

I believe that "Over the Rainbow" is probably the greatest single song of the 20th century. I'm not alone in thinking that. Runners up: Maybe I'm Amazed by McCartney, God Only Knows by The Beach Boys, Close to You written by Bacharach but as sung by Karen Carpenter. There are a great many beautiful songs in the world.

Pink + White by Frank Ocean is a very pretty song
