Just found this great web service. [url]http://analyze.echonest.com/AudioAnalysis.html[/url]
Allows you to upload a song and get the song’s structure as an xml file. No idea how to massage the data so that touch understands it, but this is currently the easiest way to get some nice meta-data for your tunes.
For those interested, there’s now a python based (offline) remix API
code.google.com/p/echo-nest-remix/
An overview for remix API and the webservice can be found here: lindsay.at/work/remix/overview.html
nice! I should try uploading a track via the Web DAT again…
