CMV: Songs sung "in round" are irritating and songs sung in such a way do not meaningfully benefit from this.

This is my first CMV, so forgive me if I blunder.

Songs sung "in round" have certain members of the chorus sing, and then a short time later the remainder of the chorus sings the same bit, so that the harmonies match but words differ.

My opinion is that such songs are irritating, and singing a song in round does not add any meaningful benefit to the song. This relates to the way the song sounds to the listener. If it somehow benefits the singers then that's good for them but that portion does not relate to my opinion.

My view could be changed with an example of a song which is significantly improved by rounds, or a theoretical argument without example that would demonstrate how a song COULD be significantly improved by rounds.
