Feature/plugin/software to detect music and dub over it? (music detection)

Greetings. Does anyone know of a way to automatically detect when music (not speech or other sounds) is playing from a particular audio source, and either dub over it with different audio or simply mute it? Basically, I'm looking for a music detection tool. Example: I'm streaming a NASA launch, but the NASA feed contains segments of music which will get flagged with copyright claims. My desire is to retain the normal feed audio, except when music plays in which case I want to mute the feed audio and replace it with my own copyright-free soundtrack.

I'm currently using Open Broadcaster Software, with RadioDJ and MB Recaster for audio.
