## Overview

MusicMatch is a Django music-recognition web application. A user uploads or records a short clip; the browser sends it to Django, where the view invokes fingerprint matching and returns song details for display. A separate ingestion route loads catalog metadata and stores generated fingerprints. The README describes MySQL-backed matching; sampled code shows SQL helpers and Django models. The upload view appears to overwrite its song result before responding, so the intended result flow is documented but may not work as written. Some template and routing connections are inferred only where explicit evidence supports them.

Main entry points: [`application/views.py`](https://github.com/vasishta-04/musicmatch/blob/main/application/views.py) (Upload and catalog views), [`application/find_song.py`](https://github.com/vasishta-04/musicmatch/blob/main/application/find_song.py) (Audio fingerprint matcher), [`static/script.js`](https://github.com/vasishta-04/musicmatch/blob/main/static/script.js) (Audio capture and display), [`application/db.py`](https://github.com/vasishta-04/musicmatch/blob/main/application/db.py) (Fingerprint ingestion)
