Oh, absolutely. I just wanted to spell it out a bit more.
One of things that becomes clear as you get more experience and depth-of-knowledge about music is how the professional songwriters (the broadway folks, the one’s who write songs for pop stars and jazz artists) absolutely smoke the rock bands of the day (whatever day that might be). Both in terms of cleverness of lyrics, content, clarity of idea and musical talent the pros kick ass.
Hell, something most people don’t realize…
Bob Donough, the guy who wrote most of the early ‘Schoolhouse Rock’ songs was a talented jazz songwriter long before he got that gig. I picked up a SR songbook several years ago figuring I could add them to the mix and get some easy laughs at parties…
THOSE DAMN THINGS ARE A BITCH AND A HALF TO PLAY. Especially on guitar. Yet they sound so clean, natural and easy to the ear.
Bumping the thread to gloat about the mix CD it inspired me to make:
- This Year’s Kisses (Billie Holiday)
- You Do Something to Me (Benny Goodman)
- Begin the Beguine (Artie Shaw)
- The Man I Love (Zoot Sims)
- S’Wonderful (Sarah Vaughan
- After You, Who (Jody Watley)
- Oh, Lady Be Good (Nat King Cole and Count Basie)
- Blue Skies (Duke Ellington)
- S’Wonderful (Stan Getz)
- I Got Rhythm (Django Reinhardt and Stephane Grappelli)
- Anything Goes (Tony Bennett and Count Basie)
- Embraceable You (Charlie Parker and Miles Davis)
- Fascinatin’ Rhythm (Antonio Carlos Jobim)
- The Song Is Ended (Louis Armstrong and the Mills Brothers)
- Nice Work If You Can Get It (Billie Holiday)
- Down in the Depths (Lisa Stansfield)
- From This Moment On (Jimmy Sommerville)
- I’ve Got You Under My Skin (Stan Getz)
- Marie (Tommy Dorsey with Frank Sinatra)
- I Got Rhythm (Ernestine Anderson)
- Let’s Do It (Billie Holiday)
- Embraceable You (Joe Williams)
- So In Love (Caetano Veloso)
Yeah, the duped songs are all on purpose. I couldn’t pick between versions. 
Also not one of the top group, but I think John Kander and Fred Ebb are definitely honorable mentions. They wrote for Broadway from the early '60s through the '70s.
Chicago (film and stage) and Cabaret (ditto) are their two most well known.
They wrote for several movies, including Funny Lady and New York, New York (including the theme song made famous by Frank Sinatra). They also did the TV specials Liza with a Z and Ol’ Blue Eyes is Back. They wrote several other Broadway shows, including Zorba, The Happy Time, and Steel Pier. They both won Kennedy Center Honors in 1998. Fred Ebb died late last year.
