Agreed, this is a lovely example.  It uses the Echonest API, which is
a web service API so unfortunately all the really interesting stuff is
hidden behind the web service.

Here is a quick shell script that does the same thing using only free

You'll need vamp-simple-host, the Vamp aubio plugins (or the QM plugin
set, but that doesn't meet the licensing requirement) and Rubber Band
v1.5.0.
