Share the songs that move you (from musicals).

For starters, how about the Kern/Hammerstein and Rogers/Hammerstein songs, many of them prospective love songs:

Make Believe (Show Boat)

Some Enchanted Evening (South Pacific)

If I Loved You (Carousel)

Something Wonderful, I Have Dreamed (The King And I)

Climb Every Mountain (Sound Of Music)

and from Stephen Sondheim:

Maria (West Side Story)

Not While I'm Around (Sweeny Todd)

No More (Into the Woods)

Oops, I forgot Sunday (Sunday In The Park With George) by Sondheim!

I left out “Somewhere,” Leonard Bernstein & Stephen Sondheim, West Side Story, and “Send In the Clowns,” Stephen Sondheim, A Little Night Music.  
I’m sure I’ve still left out a lot more.
