(on her track "Success(Has Made a Failure of our Home")
Sinéad: If Ireland had not been invaded by the English, which was done for money, the Irish people wouldn't be in the amount of trouble that they are in at the moment and I wouldn't have been abused as a child... and neither would anybody else. So what I am saying is that through my own personal experience, I've learned that success has made a failure of our home.
(on coming out in 1999)
Sinéad: I'm a lesbian ... although I haven't been very open about that and throughout most of my life I've gone out with blokes because I haven't necessarily been terribly comfortable about being a lesbian. But I actually am a lesbian.
(on comparing her later and earlier albums)
Sinéad: When you're young, you don't really know quite what you're aiming at. You're very impulsive and acting on impulse, which is very important and valuable. But you're kind of swimming in a blind sea. When you get older, you have more of a sense of direction.
(about her switch to Rastafarian music in 2005)
Sinead: I was longing for hymns and religious songs that weren't so boring and that also didn't perpetuate this kind of false idea of God, which I felt Catholicism did at the time. So I was always interested in the idea of rescuing God from religion and the idea of singing as prayer. Rasta music is the only kind of music that I think really gets that across. You feel the spirit of God alive in that music.
Sinéad: To say what you feel is to dig your own grave.
Sinéad: (Directed at Pope John Paul II) Fight the real enemy.
Sinéad: We have a tradition of passing our history orally and singing a lot of it and writing songs about it and there's kind of a calling in Irish voices when they're singing in their Irish accent.
Sinéad: I've been trying to grow it, but someone came up to me and asked if I was Enya. I was so shocked, I shaved all my hair off.
