Joss Stone has claimed Lily Allen can't sing.

The 22-year-old soul singer - who recorded her new album Colour Me Free in her mother's live music bar Mama Stone's in a week - believes music should be shared for free whenever possible, while Lily has campaigned vehemently to make internet file sharing a criminal offense.

Joss said: "She needs to sell records because she's not a singer, and that's not an offense to her because I think that she knows that too."

She added: "I think she's a performer and she's more of a personality than she is a singer. But I think when musicians are really making real music people come to the show and that's what we make our money from, from playing live. And I think it's probably harder for an artist like Lily and any other pop acts. It's really about the track and about their personality and their celebrity and that's how they make their money is selling those records.

"So the downloads - she's not going to win that fight. None of us will win that fight. So let's just accept it and let's see it as something that can be beautiful and it might change music for the better. It might sort the weeds from the flowers."

Joss added that she makes music purely for enjoyment.

She said: "Who said that musicians have to be millionaires? Who made this a rule? We don't need that much money. We just don't. We only need enough to make music and to eat and to go on tour."
