I can't speak to motab tunes. Never really listened to them.
My Grandmother's favorite hymn was "Have I done any good in the world today?"
"Oh hush thee my baby" has been the go to lullabye for generations. My grandmother and mother sang it to me. The first time I held my granddaughter and she fussed I automatically sang it to her without even thinking.
As for the worst. "Follow the prophet" grates on me and I can't stand the melody.
