"Jesus Christ Superstar" (JCS)-- [of course, I had quite the crush on the Broadway/Film version lead, Ted Neeley, so there is that. LOL ]

"Oh What a Beautiful Morning"-- Oklahoma

Many others for whom the film or theater production has gotten a little overdone and could benefit from some "time outs"...

The Finale, where the roll call of the States is taken, always gives me goosebumps.

So beautiful and romantic.

A song from My Fair Lady, it always reminds me of being young and in love. Come to think of it Get me to the Church on Time for the same musical is great too.

The Sound of Music is my favorite musical but my favorite song from a musical and one of my favorite songs ever is On the Street Where You Live (My Fair Lady).

Having said that, I also love Edelweiss and Something Good, The Sound of Music....

It's such a simple song but beautifully conveys the magic of being in love.

was the first one that grabbed me when I was a child so I will stick with that

Also
I Like to be in America

Quest For Camelot. If you don’t want to listen to it then read the lyrics.

"The Begat," from Finnian's Rainbow
"Gesticulate," from Kismet
"I Shoulda Known Better," from Help

-- Mal

Here's an example of a quality song in a superb musical:

from West Side Story

My fave from that show is So in Love. I’d love to find a tango arrangement of that song.

Everybody cut everybody cut, everybody cut FOOTLOOSE

If you’re 65 or older get on that dance floor. If your, oh, in your 40s or so stand back and watch.

"Hang the Bastard" from Cannibal! The Musical!

"Somewhere", from West Side Story,

And "My Favorite Things" from The Sound of Music.

But I wouldn't say I have a favorite song from it. It's just the whole thing altogether is so great! I've heard it saud that writers can be divided into two groups: 1. Shakespeare. And 2. All the rest. I feel the same about West Side Story.

died. For artistry, I love Revelations but for sheer joy, it's got to be Wade in the Water. He was a genius.

Rocky Horror Picture Show, of course!

Ole Man River but I love all of the music.

But then, there is the Lion King and the "Circle of Life"
Oh, and don't forget "Annie Get Your Gun" and uh oh, only one? I could go on and on. I loved every musical I ever saw.

Guess it's singular.

There are too many to pick a favorite musical (or song) but this one is way up there!

Many hundreds of wonderful songs. My first thought was some from Fiddler on the Roof. I Dreamed a Dream was already mentioned.

Anne Hathaway put such emotion into it.

Such a beautiful musical.

Jesus Christ Superstar with the incomparable Carl Anderson as Judas.

Anything from Pippin, really. This video has rehearsal and performance footage from the 2012 revival production. Morning Glow kicks in at 44 seconds.

The first; so joyful, expansive.
The other; so poignant.

And from Bernstein's theater piece (that had songs) Mass: "Simple Song".

"Easy To Be Hard" from Hair.

from "Oklahoma".

From the movie on the plane when I got out of Navy boot camp in San Diego in January 1966. I was on the way to catch my ship in Norfolk, Virginia.

Hadn't seen ANY movie for months, so this one made a special memory.

From the music man

Original.

A meaningful song.

It floored me the first time I heard it by Richard Kiley on the Ed Sullivan show. Still give me goosebumps.

I love the whole opera/musical, but the overture is stunning.

The song that always makes me cry is “Could we start again please?”
Followed very closely by “I don’t know how to love him” which perfectly describes most of my relationships with men.

We've seen the play twice, and I'd love to see it again! Is this the best song from Hamilton? I'd say no, but so darn much fun!

What comes next?

Little Shop of Horrors

The SOM is my heart, but I’d like to give a big shout out to Guys and Dolls - the film. Brando, Simmons, Sinatra…the entire cast. Adelaide. Sweet Adelaide!! And of course, Brando and Simmons off on that crazy night. I just love it.

Also it's Liverpool's song.

Somewhere and Maria - West Side Story
Send in the Clowns - A Little Night Music
They Call the Wind Mariah - Paint Your Wagon
Cell Block Tango - Chicago
Seasons of Love - Rent
76 Trombones / Goodnight, Irene - The Music Man
We Don't Talk About Bruno - Encanto

From Popeye.

Also 'I am One' from Quadrophenia.
"I got a Gibson without a case, but I just can't get that even tan look on my face.
Ill fitting clothes and I blend in the crowd. Fingers clumsy, voice too loud.
But I'm one. I am one!"

I saw them play it at The Filmore East with The Joshua Light show in Oct '69.
Fantastic!

By The Who from Quadrophenia.

When I saw them during the time they played Quadrophrenia they never played this song. I love Quad, but was disappointed about that.

Forward 1982 their "last" tour at the old Shea Stadium: don't remember what song has finished, and we're sitting there. The place is sort of noisy.
Suddenly I hear the quiet opening of piano notes.
I sort of gasp, and grab my sister's hand...and she gets annoyed...like "wth?".
I said, "Listen!" Then she gasped, and grabs mine back. Finally LROM live!
It was glorious!

Movie musicals annoy the heck out of me, they always have. I just can't stand interrupting dialog when they burst into song. RHPS is really the only musical I've ever enjoyed. Who could resist Tim Curry in fishneta? I tolerated "The Sound of Music" when I was a kid So I'm weird, lol.

Edited to add: I forgot about Tommy. That one was good, too. Whoops.

All of the favorites posted above are good wonderful suggestions. I love Put on Your Sunday Clothes from Hello Dolly and Sunday from Sunday in the Park With George.

probably my first choice from the musical would be "the american & florence/nobody's side", although "opening ceremony", "the deal", and "one night in bankok" are high on the list.

(give me some assasins or sweeny toddy for overall favorite musicals)

Especially love Embassy Lament and One Night in Bankok

(i understand how the embassy staff feels)

but had a well worn vinyl then CD then flac ripped digital files to listen to!

Gee, Officer Krupke is one that hasn't been mentioned that I really like
