Tori Amos believes that Lady GaGa's success won't last and she'll never achieve the kind of iconic status enjoyed by artists like Neil Young.

The 46-year-old believes that GaGa is the perfect tonic for the difficult global climate but that's about all.

She tells The Sun: "She's what I call a meteor - singers who entertain people for a while. Hey, there's nothing wrong with that.

"But then there are people like Neil Young who show up at Glastonbury 40 years into their career. And that's a very different kind of artist.

"The question is, will Lady GaGa be playing alongside Neil Young at Glastonbury in 20 years time? She wants to entertain people. Right now, half the world is depressed and they need to be entertained. So her timing's perfect."
