These ten come to mind. If limited to ten I might at other times make different choices. I love many hymns.

in no particular order, here's my list of top 11. (Christmas Carols are at the bottom. They are kind of in a class of their own.)
I could also give so many honorable mentions...

Let All Mortal Flesh (Picardy)
O Sacred Head Surrounded (Passion Chorale, or, Es tut Mich Verlangen)
Glory Be to Jesus (Viva Viva Jesu)
Ah, Holy Jesus (Herzliebster Jesu)
God, We Praise You (or any other good text to the tune Nettleton)
Hail, Holy Queen Enthroned Above (Salve Regina Coelitum)
How Great Thou Art (not as the schmaltzy hymn, but either the melody line acapella or rocked up somehow.)
Once in Royal David's City (Irby)
The First Noel (The First Nowell)
Away in a Manger (Cradle Song)
O Come, All Ye Faithful (Adestes Fideles)

Interesting choice with the Warner, Ralph. We've done that one on occasion. Have it on the podium now, as a matter of fact. For the ages? Who knows?

Yes. Hyfrodol is one of those tunes that like some photos can suffer from overexposure.

De gustibus non est disputandum..... providing it is 'gustibus' to start with!

I don't know why people use that Latin phrase to justify the improper selection of music in the liturgy... Please explain.

haha, Paul, that's funny.
yes, I realize these tunes are only our preferences, but still, I think this is quite an interesting thread. I think NPM or someone takes a poll on favorite songs, and of course Eagles Wings et al are on it, so this thread is great to see some other ideas of what actually are good songs. (for example, very cool that Love Unknown has been posted by several people!)
wouldn't that be interesting to take a huge poll on favorite hymns/tunes from the whole CMAA membership? hmm... (well, as long as we could avoid getting into nit-picky arguments over Latin chants verse hymns...oooh, maybe we should have two different polls!)

My source says only that it is of XVII. cent. origin and alludes to a similar prhase, quot homines, tot sententiae, which is attributed to Terrence and quoted by Cicero. (Cf. A Dictionary of Foreign Words & Phrases..., ed. Alan Bliss.)

I'm with you on EBENEZER, M. Jackson. If it had been composed in our era and I heard it first as a "drop the needle, guess the composer" quiz, I'd likely respond "Tom Conry." That's a melody with agenda.
I'm also actually not surprised by the scarcity of responses, for two reasons. We don't really traffic in "borrowed" hymns here in the forums, it's not our raisinduhtruh; and there are way too many great hymn melodies out there for us to boil down to a desert island list.

Dear Francis:
where or who publishes the 'Jerusalem' set to the magnificat text?
Thanks...

Samuel the Priest by Billings. My ancestors probably attended the funeral for which the piece was composed
When Jesus Wept - Emmaus
Jordan - I am on a Billings roll.
Os Justi Meditabitur
The Pange Lingua we used to sing on Holy Thursday before younger priests came along.
Ah Holy Jesus
There is also a version of Watt's Cadle Song sung with the tune to RESTORATION (Come Ye Sinners Poor and Needy which is a one I love as well. My Protestant ancestors calling))

Thanks, Francis!
