Why Sinead O'Connor Will No Longer Sing 'Nothing Compares 2 U'

The singer said she will retire the hit song after 25 years.

She added, "After twenty-five years of singing it, nine months or so ago I finally ran out of anything I could use in order to bring some emotion to it. I don't want audiences to be disappointed coming along to a show and then not hearing it, so am letting you know here that you won't."

"I'd be lying. You'd be getting a lie. My job is to give you honesty. I'm trained in honesty. I can't act. It just isn't in my training. I have ceased singing other songs over the years for the same reason," she wrote.
