What to sing, what to sing...? [UPDATED!]

Update: Apparently, I'm not the only thinking about this.  http://forum.musicasacra.com/forum/discussion/4447/150-indispensable-catholic-hymns
As someone noted, sounds a lot like the Adoremus Hymnal, which we use/used at Latin Mass for years.

I've been thinking of a basic, "Must Know" list of music for our group - the sorts of music pieces that we should be able to sing at the drop of a hat, whenever necessary.

Below that list.  Maybe you want to check off the ones you already know, the ones you've sung but maybe didn't stick, & the ones that you've never heard before.  Let me know what you think.

(N.B.: PBC refers to the 2nd edition of the Parish Book of Chant (download the PDF HERE)):
