I've been interested in searching for music modules that I knew were used in some YouTube videos for a while but only recently realized that this was feasible for large collections of modules e.g. the modarchive.
I recently hacked together a Python script using the dejavu project that is capable of (slowly)
https://github.com/eqy/molasses searching through large libraries of music modules with nearly 100% coverage. On an i5-2520M, it's possible to search through the entire 2007 snapshot of archive in ~4 days.
Here's a short demo video showing how the search process works:

I'm also open to pull requests if people want to make the project an actual thing or just clean up the interface.
If you have a wav/mp3 sample of a module you're desperately trying to find, let me know and I'll see how much CPU time I have to spare.
If you're interested in the backstory of how this came together, there's a long blog post here:
