For years I've been quite fond of this contemporary setting of the O Antiphons by David Haas. They are offered as the intercessions at Evening Prayer in his collection "Light and Peace." I think the melodies of the verses are light and engaging.
This video was uploaded just a few days ago, and although the performance has some miking mishaps, I think it's nonetheless easy to see that this could be an effective "bridge" piece towards chant, and an accessible and prayerful use of traditional texts in parishes.
