# Spotify-Downloader

[![Coverage Status](https://codecov.io/gh/ritiek/spotify-downloader/branch/master/graph/badge.svg)](https://codecov.io/gh/ritiek/spotify-downloader)
[![Docker Build Status](https://img.shields.io/docker/build/ritiek/spotify-downloader.svg)](https://hub.docker.com/r/ritiek/spotify-downloader)
- Downloads songs from YouTube in an MP3 format by using Spotify's HTTP link.
- Can also download a song by entering its artist and song name (in case if you don't have the Spotify's HTTP link for some song).
- Automatically applies metadata to the downloaded song which include:
- Title
- Artist
- Album
- Album art
- Lyrics (if found on http://lyrics.wikia.com)
- Album artist
- Genre
- Track number
- Disc number
- Release date
- And more...
- Works straight out of the box and does not require to generate or mess with your API keys.
That's how your music library will look like!

## Installation
- **This tool supports only Python 3**, Python 2 compatibility was dropped
because of the way it deals with unicode.
If you need to use Python 2 though, check out the (old) `python2` branch.
- Note: `play` and `lyrics` commands have been deprecated in the current branch
since they were not of much use and created unnecessary clutter.
You can still get them back by using `old` branch though.
### Debian, Ubuntu, Linux & Mac
```
$ cd
$ git clone https://github.com/ritiek/spotify-downloader
$ cd spotify-downloader
$ pip install -U -r requirements.txt
```
**Important:** if you have installed both Python 2 and 3, the `pip` command
could invoke an installation for Python 2. To see which Python version `pip`
refers to, try `$ pip -V`. If it turns out `pip` is your Python 2 pip, try
`$ pip3 install -U -r requirements.txt` instead.
You'll also need to install FFmpeg for conversion
(use `--avconv` if you'd like to use that instead):
Linux: `$ sudo apt-get install ffmpeg`
Mac: `$ brew install ffmpeg --with-libmp3lame --with-libass --with-opus --with-fdk-aac`
If it does not install correctly, you may have to build it from source.
For more info see https://trac.ffmpeg.org/wiki/CompilationGuide.
### Windows
Assuming you have Python 3
([preferably v3.6 or above to stay away from Unicode errors](https://stackoverflow.com/questions/30539882/whats-the-deal-with-python-3-4-unicode-different-languages-and-windows)) already installed and in PATH.
- Download and extract the [zip file](https://github.com/ritiek/spotify-downloader/archive/master.zip)
from master branch.
- Download FFmpeg for Windows from [here](http://ffmpeg.zeranoe.com/builds/).
Copy `ffmpeg.exe` from `ffmpeg-xxx-winxx-static\bin\ffmpeg.exe` to PATH
(usually C:\Windows\System32\) or just place it in the root directory extracted
from the above step.
- Open `cmd` and type `$ pip install -U -r requirements.txt` to install dependencies.
The same note about `pip` as for Debian, Ubuntu, Linux & Mac applies.
## Instructions for Downloading Songs
**Important:** as like with `pip`, there might be no `$ python3` command.
This is most likely the case when you have only Python 3 but not 2 installed.
In this case try the `$ python` command instead of `$ python3`,
but make sure `$ python -V` gives you a `Python 3.x.x`!
- For all available options, run `$ python3 spotdl.py --help`.
```

```
#### Download by Name
For example
- We want to download Fade by Alan Walker,
simply run `$ python3 spotdl.py --song "alan walker fade"`.
- The script will automatically look for the best matching song and
download it in the folder `Music/` placed in the root directory of the code base.
- It will now convert the song to an mp3 and try to fix meta-tags
and album-art by looking up on Spotify.
#### Download by Spotify Link (Recommended)
For example
- We want to download the same song (i.e: Fade by Alan Walker) but using
Spotify Link this time that looks like `https://open.spotify.com/track/2lfPecqFbH8X4lHSpTxt8l`,
you can copy it from your Spotify desktop or mobile app by right clicking
or long tap on the song and copy HTTP link.
- Run `$ python3 spotdl.py --song https://open.spotify.com/track/2lfPecqFbH8X4lHSpTxt8l`,
it should download Fade by Alan Walker.
- Just like before, it will again convert the song to an mp3 but since we used
a Spotify HTTP link, the script is guaranteed to fetch the correct meta-tags and album-art.
#### Download by File
For example
- We want to download `Fade by Alan Walker`, `Sky High by Elektromania`
and `Fire by Elektromania` just using a single command.
Let's suppose, we have the Spotify link for only `Fade by Alan Walker` and
`Fire by Elektromania`.
No problem!
- Just make a `list.txt` in the same folder as the script and add all the
songs you want to download, in our case it is
(if you are on Windows, just edit `list.txt` -
i.e `C:\Python36\spotify-downloader-master\list.txt`)
```
https://open.spotify.com/track/2lfPecqFbH8X4lHSpTxt8l
elektromania sky high
https://open.spotify.com/track/0fbspWuEdaaT9vfmbAZr1C
```
- Now pass `--list=list.txt` to the script, i.e `$ python3 spotdl.py --list=list.txt`
and it will start downloading songs mentioned in `list.txt`.
- You can stop downloading songs by hitting `ctrl+c`, the script will automatically
resume from the song where you stopped it the next time you want to download
the songs present in `list.txt`.
- Songs that are already downloaded will prompt you to overwrite or skip. This behavior can be changed by
passing `--overwrite {prompt,skip,force}`.
#### Download by Playlist Link
- You can copy the Spotify URL of the playlist and pass it in `--playlist` option.
Note: This method works for public as well as private playlists.
For example
- `$ python3 spotdl.py --playlist https://open.spotify.com/user/nocopyrightsounds/playlist/7sZbq8QGyMnhKPcLJvCUFD`
- The script will load all the tracks from the playlist into `<playlist_name>.txt`
- Then you can simply run `$ python3 spotdl.py --list=<playlist_name>.txt`
to download all the tracks.
#### Download by Album Link
- You can copy the Spotify URL of the album and pass it in `--album` option.
For example
- `$ python3 spotdl.py --album https://open.spotify.com/album/499J8bIsEnU7DSrosFDJJg`
- The script will load all the tracks from the album into `<album_name>.txt`
- Then you can simply run `$ python3 spotdl.py --list=<album_name>.txt`
to download all the tracks.
#### Download by Username
- You can also load songs using Spotify username if you don't have the playlist URL.
(Open profile in Spotify, click on the three little dots below name,
"Share", "Copy to clipboard", paste last numbers or text into command-line:
`https://open.spotify.com/user/0123456790`)
- Try running `python3 spotdl.py -u <your_username>`, it will (only) show all your
public playlists (which excludes collaborative and private playlists).
- Once you select the one you want to download, the script will load all the tracks
from the playlist into `<playlist_name>.txt`.
- Run `$ python3 spotdl.py --list=<playlist_name>.txt` to download all the tracks.
#### Specify the Target Directory
If you don't want to download all the songs to the `Music/` folder relative to the
`spotdl.py` script, you can use the `-f`/`--folder` option.
E.g. `$ python3 spotdl.py -s "adele hello" -f "/home/user/Music/"`.
This works with both relative and absolute paths.
## Config File
At first run, this tool will generate a `config.yml` in root directory
of the code base with default options. You can then modify `config.yml`
to override any default options.
Also note that config options are overridden by command-line arguments.
If you want to use custom `.yml` configuration instead of the default one, you can use `-c`/`--config` option.
E.g. `$ python3 spotdl.py -s "adele hello" -c "/home/user/customConfig.yml"`
## Set YouTube API Key
By default this tool will scrape YouTube to fetch for matching video tracks.
However, you can optionally use YouTube API for faster response time.
To do this, [generate your API key](https://developers.google.com/youtube/registering_an_application)
and then set it in your `config.yml`.
