If I'm at a wedding, or party I have to leave the dancefloor, or room when I inevitably hear:
It's raining men.
I will survive.
They both make me want to go and boil my own head in a vat.
Agree with PPs about Jess Glynn. Nasal, whiny, nails down a blackboard voice. Radio goes off immediately. As it does for anything by Ed Sheeran.
I cannot abide people that mumble in songs, Bruce Springsteen and Billie Eilish, I'm looking at you.
I hate people that cover a song and do it so badly that you want to cry.
I heard a Tori Amos cover version of Chas & Dave's London Girls the other day. It was painful. One Direction totally murdered Teenage Kicks.
Conversely, I love a cover version that really twists the original on its head and makes it sound so different, but amazing.
Disturbed's Sound of Silence and Scissor Sisters' Comfortably Numb for example. I know the latter is controversial, but I hate Pink Floyd anyway.
