My D&D bard, Roscoe, had to sing songs for various purposes. Bardic music spells require song components, but bards also get some regular spells which don't require singing. Roscoe wrote some songs for some regular spells anyway, just because.
Roscoe found a way to use a 0th-level spell (zero, not ten) to fix an evil sanctuary (the paladin in our party had totally failed to exorcise the evil).
Roscoe waited there while the paladin strove and strove to clear the place. On their way out, Roscoe flicked a prestidigitation spell over the altar to clear off all those nasty bloodstains (Roscoe likes things neat). Thus dispelling ... That was just a regular spell, no singing required, but Roscoe commemorated the event later:
"Prestidigitation
Cleans up all over creation
But can really cause a sensation
When used for evil exorcisation!"
