I wouldn't say all Christian music is boring, but there's not a lot of it I enjoy. Of course, I don't listen to much overtly religious music of any type.
OP's videos, #1 has no movement to see, forcing the attention to the audio realm as would a theologian from a pulpit; in videos #2 and #3, the visuals are promiscuous, though both could stand transcription of their lyrics.
Post #3, in the first second of the video, no one knows whether or not the performer has commanded or asked the people to genuflect. In post #4, lyrics would be appreciated.
