Note that the binaries right now have only been tested on WSL. They should run on most linux distros, and OS X, but if they don't please make an issue above.
If you're one of those cool people who compiles from source
- Install crystal-lang
(
https://crystal-lang.org/install/
) - Clone it (
git clone https://github.com/cooperhammond/irs
) - CD it (
cd irs
) - Build it (
shards build
)
- Create a
.yaml
config file somewhere on your system (usually~/.irs/
) - Copy the following into it
binary_directory: ~/.irs/bin music_directory: ~/Music filename_pattern: "{track_number} - {title}" directory_pattern: "{artist}/{album}" client_key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX client_secret: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX single_folder_playlist: enabled: true retain_playlist_order: true unify_into_album: false
- Set the environment variable
IRS_CONFIG_LOCATION
pointing to that file - Go to
https://developer.spotify.com/dashboard/
- Log in or create an account
- Click
CREATE A CLIENT ID
- Enter all necessary info, true or false, continue
- Find your client key and client secret
- Copy each respectively into the X's in your config file
- Run
irs --install
and answer the prompts!
You should be good to go! Run the file from your command line to get more help on usage or keep reading!
You may have noticed that there's a config file with more than a few options. Here's what they do:
binary_directory: ~/.irs/bin
music_directory: ~/Music
search_terms: "lyrics"
filename_pattern: "{track_number} - {title}"
directory_pattern: "{artist}/{album}"
client_key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
client_secret: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
single_folder_playlist:
enabled: true
retain_playlist_order: true
unify_into_album: false
binary_directory
: a path specifying where the downloaded binaries should be placedmusic_directory
: a path specifying where downloaded mp3s should be placed.search_terms
: additional search terms to plug into youtube, which can be potentially useful for not grabbing erroneous audio.filename_pattern
: a pattern for the output filename of the mp3directory_pattern
: a pattern for the folder structure your mp3s are saved inclient_key
: a client key from your spotify API applicationclient_secret
: a client secret key from your spotify API applicationsingle_folder_playlist/enabled
: if set to true, all mp3s from a downloaded playlist will be placed in the same folder.single_folder_playlist/retain_playlist_order
: if set to true, the track numbers of the mp3s of the playlist will be overwritten to correspond to their place in the playlistsingle_folder_playlist/unify_into_album
: if set to true, will overwrite the album name and album image of the mp3 with the title of your playlist and the image for your playlist respectively
In a pattern following keywords will be replaced:
Keyword | Replacement | Example |
---|---|---|
{artist} |
Artist Name | Queen |
{title} |
Track Title | Bohemian Rhapsody |
{album} |
Album Name | Stone Cold Classics |
{track_number} |
Track Number | 9 |
{total_tracks} |
Total Tracks in Album | 14 |
{disc_number} |
Disc Number | 1 |
{day} |
Release Day | 01 |
{month} |
Release Month | 01 |
{year} |
Release Year | 2006 |
{id} |
Spotify ID | 6l8GvAyoUZwWDgF1e4822w |
Beware OS-restrictions when naming your mp3s.
Pattern Examples:
music_directory: ~/Music
filename_pattern: "{track_number} - {title}"
directory_pattern: "{artist}/{album}"
Outputs: ~/Music/Queen/Stone Cold Classics/9 - Bohemian Rhapsody.mp3
music_directory: ~/Music
filename_pattern: "{artist} - {title}"
directory_pattern: ""
Outputs: ~/Music/Queen - Bohemian Rhapsody.mp3
music_directory: ~/Music
filename_pattern: "{track_number} of {total_tracks} - {title}"
directory_pattern: "{year}/{artist}/{album}"
Outputs: ~/Music/2006/Queen/Stone Cold Classics/9 of 14 - Bohemian Rhapsody.mp3
music_directory: ~/Music
filename_pattern: "{track_number}. {title}"
directory_pattern: "irs/{artist} - {album}"
Outputs: ~/Music/irs/Queen - Stone Cold Classics/9. Bohemian Rhapsody.mp3
At it's core irs
downloads individual songs. It does this by interfacing
with the Spotify API, grabbing metadata, and then searching Youtube for a video
containing the song's audio. It will download the video using
youtube-dl
, extract the audio using
ffmpeg
, and then pack the audio and metadata together
into an MP3.
From the core, it has been extended to download the index of albums and playlists through the spotify API, and then iteratively use the method above for downloading each song.
It used to be in python, but
- I wasn't a fan of python's limited ability to distribute standalone binaries
- It was a charlie foxtrot of code that I made when I was little and I wanted to refine it
crystal-lang
made some promises and I was interested in seeing how well it did (verdict: if you're building high-level tools you want to run quickly and distribute, it's perfect)
