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.

With Twitter and other social networking tools, you can get a lot of advice from great people. I learn more from Twitter than any survey or discussion with a big company.

With Spotify, people don't get it until they try it. Then they tell their friends.

I had two passions growing up - one was music, one was technology. I tried to play in a band for a while, but I was never talented enough to make it. And I started companies. One day came along and I decided to combine the two - and there was Spotify.

In general, people are comfortable sharing their music. There are two exceptions, though - Lady Gaga and Britney Spears.

We led with our conviction rather than rational, because rational said it was impossible.

I'm not an inventor. I just want to make things better.
