Who wrote the Sinead O`Connor hit 'Nothing Compares 2 U'?

Prince wrote the hit song "Nothing Compares 2 U." Originally recorded by Prince's side project, The Family, in 1985, the song gained widespread popularity when Sinead O'Connor released her version in 1990. While O'Connor's hauntingly beautiful rendition made the song a global success, it was Prince's original composition that captured the essence of heartbreak and longing, creating an enduring and emotionally resonant piece of music.
