I don't know if you're being sarcastic or not ... and I don't consider myself a protestant, but I DO know we, in out Baptist congregation, are aware of vain repetition and strive to not perform it
yes knarf some sarc since as a Catholic we have had the term tossed our way innumerable times.
I understand the reverence most folks show in their prayers and songs that St Augustine said He who sings prays twice about 1,600 years ago.
Prayer is all about the eternal, omnipotent Creator and us mere mortals and our relationship to Him.
Most Christian music in the last few hundred years is kitsch, pure and simple.
Ad Majoram Dei Gloriam
