This is why I highly dislike what they use in the big churches in russia
It is always fast, happy, jumpy, western notation singing
when the Patriarch of Georgia visited Russia, I was very happy when sometimes they did some Georgian style chants it sounded much more solemn, contemplative, and what really made it full was one of the old, humble looking bishops standing there seemed to be whispering something over and over to himself.... I would assume the jesus prayer. I wish he was patriarch of moscow... it almost made me cry
Also I saw a video of the Patriarch of Moscow visit the Valaam monastery, and I was very happy to hear some of the Valaam chants. Of course they put in some of the modern russian singsong chants, but at least about 50% of the time when they had the valaam chants i felt contemplative/prayerful.
