Kate Nash writes songs on her phone.

The 'Foundations' singer - who also plays bass in punk band The Receeders - came up with the beginning of her hit tune 'Mansion Song' spontaneously and had to write the lyrics in a text message.

She told Beatweek magazine: "I wrote that on a text message on the phone because it really just came straight out of me, didn't need to edit it or anything, really. I'm not really good at editing my work. I'm better at just doing it."

Kate says the most satisfying thing about songwriting for her is having the opportunity to express herself.

She said: "Too many people are bland and afraid to have an opinion, because people will say, 'Oh, it's so shocking, oh it's this,' or it'll be reactionary, and it's like, 'Who cares?' "

The singer - who recently released her new album 'My Best Friend is You' - is also dismissive of the current crop of successful young female British artists, such as Pixie Lott and Little Boots.

She explained: "I actually think it's so damaging when I hear people saying, 'Oh it's so great - all these young female artists are doing so well.'

"I'm like, 'No, because big manufactured labels think that's what sells.' So they invent a bunch of pretty girls to do something alternative and build their indie careers when they've been signed to a major the whole time."
