I will say Hallelujah when Leonard Cohen’s Hallelujah is covered no more. I heard K.D. Lang’s horrid version of it today on Jools Holland and realized I never want to hear another cover of it again, ever. I capitalized her name as penance, since she seems to hate that.
ps. of course, Jeff Buckley’s version that brought the song to prominence WAS indeed a cover, but it is the definitive cover, and best version.
