Late last week, we first wrote about SoundTracking , a new iPhone application from Schematic Labs that allows you to easily share not only the music you're listening to, but the music you're listening to in the context that you're listening to it in. Yesterday at the SXSW conference in Austin, Texas, I got a chance to sit down with co-founder Steve Jang for his thoughts on the app and the space. Jang talks about the rise of the "mobile-first" experience, noting that phones are good enough now to match the websites that have been built for years now. And in many ways, the experience is better because mobile is so personal. Jang talks about his inspiration for SoundTracking when he was traveling around Europe and wanting to share the music he was listening to on the go, but in a way beyond text.
