A lot of times songs are very much of a moment, that you just encapsulate. They come to you, you write them, you feel good that day, or bad that day.
Mick JaggerWriting a song is like - you're writing a song all the time. It's just when it pops out. It's been there all the time. It's not something that suddenly you do it. It's always there. Suddenly, it's in the right mixture inside you to come out. Usually when you're writing on the piano or a guitar, you don't write in lyrics, on their own. To me it's very boring.
