From a personal perspective, I feel some kinds of songs lend themselves more to unaccompanied performance & if accompanied detracts/ interferes with the sentiment/ message/ phrasing of the piece.

I like to perform stuff of all shades either accompanied or otherwise from trad folk, old pop, rock, diddly-diddly tunes seshes or w.h.y. - but I can get a little miffed if when doing something like 'Pleasant & Delightful' - some 'ignoramus' may start plonking away on guitar or even worse random rattling eggs, spoons, bashing bodrhans to the extent I'll just stop & sulk & glare at them politely request they desist & qualify why.

Guess I'm not alone in this position? Anyone?
