# MusicIndexer
Pull your Spotify library and listening stats via the Spotify Web API, index a
local music library (audio tags + iTunes XML), and match the two so you can see
which tracks you own, what's missing, and your top artists/tracks/playlists — in
a Streamlit GUI.
## Features
- **Spotify backend** — OAuth (Authorization Code) login, then fetch the user
profile, liked tracks, all playlists and their tracks, long-term top tracks
and top artists, and playlist/profile cover art. Resilient paginated fetching
(follows `next`, retries dropped connections, honours `429` rate limits) with
progress bars.
- **Local backend** — index a folder of audio files via `mutagen` tags.
- **iTunes backend** — parse an iTunes Library XML export.
- **Matching** — map local tracks to Spotify tracks (fuzzy matcher; ISRC/MBID
matching planned).
- **Stats & lyrics** — generate listening stats and fetch lyrics.
- **GUI** — browse libraries as artist → album → track tables.
## Setup
Requires Python 3.13+.
```bash
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
```
### Credentials
Create an app at https://developer.spotify.com/dashboard and add
`http://127.0.0.1:8888` as a **Redirect URI**. Credentials are read from the
environment — never commit them.
```bash
cp .env.example .env
# edit .env with your client id/secret
source .env
```
`Env.py` reads `SPOTIFY_CLIENT_ID` / `SPOTIFY_CLIENT_SECRET` (plus optional
`MUSIC_LIBRARY_PATH` and `WORK_DIR`) from the environment.
## Usage
Edit `main.py` to uncomment the steps you want, then run:
```bash
python main.py
```
The flow steps (see `Flow.py`) include:
| Step | What it does |
|------|--------------|
| `fetch_spotify()` | OAuth login + download all Spotify data into `work_dir/spotify/` |
| `fetch_local()` | index local audio files into `work_dir/local/` |
| `parse_spotify_library()` / `parse_itunes_library()` / `parse_local_library()` | build normalized libraries |
| `load_libraries()` / `save_libraries()` | (de)serialize libraries to `work_dir` |
| `map_local_to_spotify()` | match local tracks against the Spotify library |
| `fetch_and_save_lyrics()` | fetch lyrics for tracks |
| `log_stats()` | generate stats |
On first `fetch_spotify()` a browser opens for the Spotify login; a local server
on `127.0.0.1:8888` catches the redirect and exchanges the code for a token.
### GUI
```bash
./gui.sh # runs: .venv/bin/streamlit run Gui.py
```
## Layout
```
main.py entry point (CLI flow)
Gui.py / gui.sh Streamlit GUI
Flow.py orchestrates fetch / parse / map / stats
Env.py config (reads credentials from the environment)
src/
Library.py data model (Library / Artist / Album / Track)
LibrarySerializer.py load/save libraries
backends/
spotify/ Web API client, OAuth, parser
local/ local-file indexer, parser, playlist generator
itunes/ iTunes XML parser
navidrome/ Navidrome backend
mappers/ local↔Spotify matching (fuzzy / search)
lyrics/ lyrics fetching
work_dir/ fetched data and serialized libraries (gitignored)
```
## Notes
- Data is cached as JSON under `work_dir/` (gitignored); re-running reuses it.
- The deprecated Spotify endpoints (audio-features, recommendations, etc.) are
not used — only currently-supported endpoints.
