"I Want You" is a song written and recorded by Elvis Costello. It was released as a single from his 1986 album Blood & Chocolate. Stephen Thomas Erlewine described it as "[among] the nastiest songs he has ever recorded, both lyrically and musically". In his album notes for the Girls Girls Girls compilation album, Costello wrote that "[t]he sound of this track was always going to be the aural equivalent of a blurred polaroid, so no apologies for the lack of fidelity. None are needed, it's just a pornographic snapshot; lots of broken glass, a squashed box of chocolates and a little blood on the wall."
