I'm here at the last keynote of SXSW, where Spotify CEO Daniel Ek is being interviewed by Wired's Eliot Van Buskirk. Ek will likely be revealing some new announcements about Spotify during this interview. I'll be live blogging my notes below. Van Buskirk kicked off the keynote by asking how many people in the audience had used Spotify, leading a significant portion of the audience to raise their hands. This was surprising, because Spotify is only widely available in Europe (you need a beta invite to use it in the US). Ek then took some time to walk the audience through the service if they haven't used it before.
