We kind of look at music as something very natural in people's lives. I mean, most of us can relate to music in some sort of shape and form, and if you think about it, most of us remember the first time we kissed someone, what kind of music was playing or the song that was playing on our friend's birthday.

I'm not saying you can't be successful in the music industry without Spotify. But when I look at the future of music, I don't think scarcity is the model anymore. We have to embrace ubiquity - that music is everywhere.

There are millions of people who consume music illegally every month. Just getting them into a legal service will make the music industry way bigger than it's ever been before.

There are half a billion people that listen to music online and the vast majority are doing so illegally. But if we bring those people over to the legal side and Spotify, what is going to happen is we are going to double the music industry and that will lead to more artists creating great new music.

For me, as someone growing up in a working-class suburb in Stockholm, I couldn't afford all the music. So back in '98, '99, I was really thinking about how I could get all the music and do it in a legal way while at the same time compensating the artist.

I realised that you can never legislate away from piracy. Laws can definitely help, but it doesn't take away the problem. The only way to solve the problem was to create a service that was better than piracy and at the same time compensates the music industry - that gave us Spotify.
