Nick Cave, easy
Can't believe no has mentioned Barbra Streisand. Fingernails on a chalkboard or a dragging tailpipe are more pleasant to listen to. Plus, she spells her first name wrong.

Morrissey, Paul Weller, Florence, Roger Daltrey, Lucy Rose, Thom Yorke.
Queen, Mika, Leo Sayer and that f*cking muppets thing that Simon Mayo always plays on fridays
Susan Boyle
