No, the people do not have music for the antiphons. I do not sing the same ones each week, I sing the proper antiphons, either from Graduale Romanum, or, when I want to do one in English, from the American Gradual. If you were doing antiphons from the Graduale Simplex (or its English translation, By Flowing Waters), you could conceivably do the same ones each week, as there are, I believe, five options for ordinary time.
A communion song that the people know may suffice as a cheat antiphon, but it is certainly not the proper antiphon, which is the first option from the GIRM.
I think that whether people enjoy singing certain songs, or what a person’s individual taste in music is, is quite beside the point. There is some music that is appropriate to liturgical action, and some that is not. Period. The propers of the Mass are actually part of the liturgy, while “songs” or hymns provide mere accompaniment.
This article expresses it much more eloquently than I can.
