smclipy

simple music cli py is a Python script designed to streamline downloading, tagging, and organizing music from YouTube. It allows you to batch-download audio, manually set metadata (including multiple artists and cover art).

Features

• Batch Downloading: Queue up as many YouTube URLs as you want before processing.
• Interactive Tagging: Prompts you for the track Title and Artists (has autocompletion). Both come prefilled: the title from the video's title, and the artists from the channel name, corrected against your known authors.
• Cover Art Cropping: Easily crop your cover art to a perfect 1:1 square ratio during the tagging process.
• Clean Cleanup: Uses a .temp directory (inside your music folder's smclipy subfolder) during the download and tagging process to keep your main library clean.

Requirements

• Python 3.12+ (handled automatically if you use uv).
• FFmpeg — required by yt-dlp to extract the audio to MP3 and embed the cover art.
• Deno — required by yt-dlp (2025.11+) to solve YouTube's JavaScript challenges during extraction. Without it, downloads may fail or have limited format availability.

Installation

pip install smclipy

Configuration

smclipy relies on a configuration file to know where to organize your files.

On first run, a default config file is created at ~/.config/smclipy/config.json and the program exits so you can edit it to your liking. To store it somewhere else, set the SMCLIPY_CONFIG environment variable to your preferred path (respects $XDG_CONFIG_HOME).

{
  "name": "smclipy",
  "path_to_music_folder": "./Music",
  "description_max_lines": 5
}

Config Breakdown

• name: The master folder name (smclipy) that will be created inside your music folder to hold all the organized artists.
• path_to_music_folder: The base directory where your music library lives (default is ./Music, relative to wherever you run the command from).
• description_max_lines: How many lines of the video description to show while tagging (default is 5).

Usage

Run it from your music library's parent directory:

smclipy <command>

Commands

• smclipy download — Batch download and tag songs from YouTube.
• smclipy crop — Scan saved covers for pillarboxed art, crop to 1:1, and re-embed into the matching MP3s.

Download flow

1. Queue URLs: Paste your YouTube URLs one by one (enter an empty line to finish).

2. Tagging Flow (Per Track):

   • The script will download the current track to Music/smclipy/.temp.
   • If a cover image is found, you will be prompted to crop it to a 1:1 ratio.
   • Enter the Title of the track (prefilled with the video's title).
   • Enter the Artist/s (prefilled from the channel name; if it matches an author already in authors.txt — ignoring case and spaces — your existing spelling is kept). To tag multiple artists, separate them using a backslash \ (e.g., Artist 1\Artist 2\Artist 3).

3. Completion: Once tagged, the final music file is moved to your designated music folder, using the following filename artist-title.mp3 (e.g., Rick Astley-Never Gonna Give You Up.mp3).

Folder Structure Example

After running the script and tagging a few songs, your output directory will look something like this:

📁 ./Music
├── 🎵 artist1-title1.mp3
├── 🎵 artist1-title2.mp3
├── 🎵 artist2-title1.mp3
├── 🎵 artist3-title1.mp3
└── 📁 smclipy
    ├── 📁 .temp         <-- (Used temporarily during processing)
    ├── 📁 covers
    ├── 📄 authors.txt
    └── 📄 songs_info.txt

Development

Clone the repo and run it from the project root with uv (set SMCLIPY_CONFIG to use your existing config.json):

uv run smclipy <command>
