spotify-auto-dl 0.1.1

Automatically download new releases from your favorite artists using spotdl

Spotify Auto Downloader

Automatically download new releases from your favorite Spotify artists to a local drive. Tracks artists you care about, downloads only songs you don't already have, and can run on a schedule to stay up to date automatically.

How It Works

1. You provide a list of Spotify artist URLs in a config file
2. On each run, the tool fetches each artist's full discography from Spotify
3. It compares against a local state file to find tracks you don't have yet
4. New tracks are downloaded as MP3s via spotdl
5. The state file is updated so those tracks are skipped on future runs

Requirements

• Python 3.10 or higher
• A Spotify Developer account (free)
• ffmpeg installed on your machine

Install ffmpeg on Mac:

brew install ffmpeg

Installation

1. Install the package

pip install spotify-auto-dl

2. Generate a starter config

spotify-auto-dl init

Creates a config.yaml in your current directory with sensible defaults. Run this once after installing.

3. Set your credentials

Create a .env file in the same directory as your config.yaml:

SPOTIFY_CLIENT_ID=your_client_id_here
SPOTIFY_CLIENT_SECRET=your_client_secret_here

See Spotify API Credentials below for how to get these.

4. Set your download folder

spotify-auto-dl set-destination ~/Music

5. Add artists and sync

spotify-auto-dl add-artist "https://open.spotify.com/artist/ARTIST_ID"
spotify-auto-dl sync

---

Spotify API Credentials

This tool uses the Spotify API to look up artist discographies. You need a free client ID and secret.

1. Go to developer.spotify.com/dashboard
2. Click Create App
3. Fill in any name and description, set the redirect URI to http://localhost
4. Open the app and copy the Client ID and Client Secret
5. Paste them into your .env file

---

Configuration

Your config.yaml controls where files are saved, which artists to track, and how downloads are formatted:

download_dir: ~/Music/spotify-auto-dl

artists:
  - name: Daniel Caesar
    url: https://open.spotify.com/artist/20wkVLutqVOYrc0kxFs7rA

schedule:
  interval_hours: 24
  run_on_start: true

output:
  format: "{artist}/{album}/{title}.{output-ext}"
  audio_format: mp3
  bitrate: 320k

To get an artist URL: open Spotify → artist page → three dots → Share → Copy Artist Link.

Rather than editing config.yaml by hand, you can use the CLI commands below.

Usage

Initialize config

spotify-auto-dl init

Creates a config.yaml in the current directory. Run once after installing.

Run a one-time sync

spotify-auto-dl sync

Run continuously on a schedule (daemon mode)

spotify-auto-dl sync --daemon

Syncs immediately on start (if run_on_start: true), then again every interval_hours hours. See Scheduling for when to use this vs cron.

Add an artist

spotify-auto-dl add-artist "https://open.spotify.com/artist/ARTIST_ID"

Looks up the artist name from Spotify automatically and appends them to config.yaml.

Change the download directory

spotify-auto-dl set-destination /Volumes/MyDrive/Music

Updates download_dir in config.yaml. Creates the directory if it doesn't exist.

Use a custom config file path

spotify-auto-dl sync --config /path/to/my-config.yaml

---

File Organization

Downloaded files are organized using the output.format template in config.yaml:

{download_dir}/
└── {artist}/
    └── {album}/
        └── {title}.mp3

For example:

~/Music/spotify-auto-dl/
└── Daniel Caesar/
    └── Freudian/
        ├── Get You (feat. Kali Uchis).mp3
        └── Best Part (feat. H.E.R.).mp3

---

State File

Downloaded tracks are recorded in ~/.spotify-auto-dl/state.json. This is how the tool knows what you already have — it prevents re-downloading songs across runs. Do not delete it unless you want to re-download everything.

---

Scheduling

There are two ways to run this tool automatically: daemon mode and cron. They accomplish the same goal differently.

Daemon vs Cron

	Daemon (--daemon)	Cron
How it works	Python process that sleeps and loops forever	OS wakes the command at a set time, runs once and exits
Requires terminal open	Yes	No
Survives reboot	No	Yes
Easy to stop	Ctrl+C	crontab -e to remove
Best for	Servers, Docker containers	Personal computers

For a personal Mac, cron is recommended. The daemon requires a terminal window to stay open and won't restart if you reboot. Cron is managed by the OS and runs reliably in the background.

---

Setting Up Cron (Recommended for Mac)

Step 1 — open your crontab

crontab -e

This opens a text editor. If it opens vim, press i to start typing.

Step 2 — add this line (runs every day at 6am)

0 6 * * * cd /path/to/your/config/folder && SPOTIFY_CLIENT_ID=your_id SPOTIFY_CLIENT_SECRET=your_secret /path/to/.venv/bin/spotify-auto-dl sync --config /path/to/config.yaml >> ~/.spotify-auto-dl/cron.log 2>&1

Replace the paths with your actual values. To find the path to the executable:

which spotify-auto-dl

The credentials must be inline because cron does not load .env files automatically.

Step 3 — save and exit

If using vim: press Esc, type :wq, press Enter.

Step 4 — verify it saved

crontab -l

Changing the schedule — edit the 0 6 * * * part:

0 8 * * *     every day at 8am
0 6 * * 1     every Monday at 6am
0 6,18 * * *  every day at 6am and 6pm

Checking the log after it runs:

cat ~/.spotify-auto-dl/cron.log

Troubleshooting

KeyError: SPOTIFY_CLIENT_ID Your .env file is missing or the variable names are misspelled. Make sure .env exists in the same directory where you run the command.

FileNotFoundError: config.yaml Run spotify-auto-dl init first, or use --config /full/path/to/config.yaml if your config is elsewhere.

A track shows as new every run The same song can have different Spotify IDs across album versions, deluxe editions, and singles. The tool checks by both ID and title to handle this, but edge cases may occur.

Downloads are slow Normal — each track requires finding a matching audio source on YouTube. The first run is the slowest since it downloads everything. Future runs only fetch new releases.
