Extracting sound spectrum data in WP7

I was very dissatisfied when I realized that the MediaLibrary's GetVisualizationData() returns a bunch of zeros on WP7. What are the other approaches I could apply in order to compute and extract sound spectrum data from my MediaLibrary's song collection ?

P.S. The way it's written suggests that I'm working on an XNA project. I would be glad to accept even Silverlight-related approaches, as this is more of a general problem I'm struggling with

You'll have to write your own algorithm. It's not exactly easy, but what you're looking for is Beat Detection (this page has some links to get you started).

EDIT: Here is some Java source-code for beat detection from the Mimim library.
