Thank you Thank you Thank you Thank you

I would have gotten lost at the first hurdle.

Although you may not be able to determine if the the music was the HPR theme or not, could you determine if there was music in a section at all ?

Say if we cut the first 3 minutes from the front and end of a episode, could it check if there was music in there ?

Quite behind on my listening, so I didn't even think to check for comments until I caught the community news show just now (just caught up to my episode last night). Frankly, I'm way over my head. My very limited understanding of the fingerprint is that it's just a timestamped list of transitions between sounds. I don't know nearly enough about signal processing generally, nor about how Echoprint encodes those transitions specifically, to even speculate how one would begin to distinguish between music and speech.
