With a net worth of $6 million, singer and songwriter Sinead O'Connor also has seen her fair share of controversy. Her net worth hasn't been to blame for this, however, instead it's been her controversial views and outspoken demeanor that O'Connor is associated with in the minds of much of the public. Her career in music began in the early 1980s, with Sinead eventually joining up with a band called Ton Ton Macoute, named for the zombies of Haitian folklore. Her work with the band eventually earned her a record deal with Ensign Records, where her first important project wound up being recording a song with legendary guitarist The Edge of U2 for the movie Captive. O'Connor continued to record music, even being allowed to produce her first album despite only being 20 years old and pregnant! But it wasn't until her second album, I Don't Want What I Haven't Got, that her breakout song was latched onto by audiences. The song, "Nothing Compares 2 U," was written by Prince and was famous for its austere music video, which featured a close-up of O'Connor sadly singing the ballad before crying a single tear. Sinead O'Connor became a big star after that, but her career descended into controversy after she infamously tore up a picture of the Pope on Saturday Night Live, an action that still carries consequences for her career to this day.
