The Music that blessed my heart most is music with a beautiful tune.
And I like a lilting tune that goes both high & low in pitch range.
Perhaps by the influence of rap/hip hop, a lot of Christian music seems to
have good words, but a flat (IMHO) boring non-tune,
recitatif.
It is like they are speaking the words more than singing them.
But for some reason, worship leaders are choosing these when they could
choose a beautiful tune (& don't).
Here is an example of what blesses my heart:
