What if instead of relying on the latest serendipity search engine to find new music you could overcome the data bottleneck in a more personal way?

Six months ago we caught a glimpse of this with Google correlate, which let you search Google trends by drawing a squiggle. Now there's a similar app for searching Spotify courtesy of Paul Lamere of The Echo Nest. You draw a shape, wavy or otherwise, of a time series and the app will return the song whose volume most closely aligns with your shape. The app can find a match from the 'Million Song Database' and provides an optional link in to Spotify so that you can listen to the song which best matches your drawing.

The app is currently constrained by the metadata available on the database, but imagine if this method of searching was expanded: what if you scrawled multiple lines for frequency, key changes or BPM and an app found the best match for the sum of your scribbles? It would be a different way of searching, a little like using automatic drawing to find the song that best matches your mood.

Better still, imagine a means of navigating the internet by drawing? This could be much appropriate way of doing it, and might be a lot more in tune with the touchscreen interfaces through which the internet is mediated to us.
