Irish singer Sinead O'Connor announced Monday that she will no longer be singing her hit song "Nothing Compares 2 U."

O'Connor wrote on Facebook: "After 25 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. ... If I were to sing it just to please people, I wouldn't be doing my job right, because my job is to be emotionally available. I'd be lying."

The announcement gained so much attention because the hit 1990 track is the very song that quickly brought her fame.

Commenters on her Facebook post seemed to have split opinions about the announcement.

One wrote: "Even if it does not stir emotion for you, it does for others. Just a consideration."

Another wrote: "You shouldn't sing a song if you don't want to."

Opinions were split on shows like "Today" as well. "Isn't singing songs to please people part of your job?" Al Roker asked.

"I appreciate her candor because she's saying, 'If that's your song, don't come,'" Savannah Guthrie said.

The song was composed by Prince, and according to Official Charts, O'Connor's rendition "has certainly earned its place in the hall of fame."

In 2009, asked about what her favorite song from the album "I Do Not Want What I Haven't Got," O'Connor told ITN:

"Probably 'Nothing Compares.' I mean, I like a lot of the other songs as well, but if you said, 'Pick one,' it'd be that one."

We understand that things change. Just don't be surprised when you hear people singing this line after this announcement:

"Nothing can stop these lonely tears from falling." (Video via iConcerts)
