Will the soloists please step forward?

I decided to tackle the problem of finding solo music in sound files that contain both solo and non-solo music.  Basically, this is a classification problem where each part of a track of music is labeled 'solo' or 'non-solo.'  It's an interesting problem because such a classifier would allow you to pull out sections of solo music out of a large pool of mixed music.  You might then, for example, attempt to classify the solo instrument.

Part 3: Execution

Part 4: Results with test music samples

Part 5: What happened?

Part 6: What next?

Addendum: Wav files, labels, and code
