Britney Spears: `I`m stubborn about my music`

The 29-year-old singer is set to release her seventh studio album, Femme Fatale, later this month, and said that she has ploughed as much of herself into this record as every single one before.

She told Rolling Stone, 'I have always been heavily involved in every album I have ever made.

'I'm very stubborn when it comes to recording and will only record songs I love, which is why it takes me a long time to make an album. I have to feel connected before I record and the song has to spark something inside me. Very few songs do that.

'I guess it's a good process because I love all of my music. I know there are a lot of artists that hate songs they recorded. I don't feel that way.'

Talking about the overall sound of the LP, she explained, 'I wanted to make a fresh-sounding album for the clubs or something that you play in your car when you're going out at night that gets you excited but I wanted it to sound different from everything else out right now.

'I also wanted to experiment with all the different types of music I love which is why you hear a mixture of pop, hip-hop and dance throughout the album. I also really wanted to play with my voice and change up my sound here and there which was really fun.'
