LyricsFinder

LyricsFinder

LyricsFinder is a modular and easily expandable Python Package that is used to extract lyrics from music. By having the ability to use a combination of a Google Custom Search Engine and a set of extractors for several sources, lyrics are attained with much higher accuracy and generally from the best desired source.

Requirements

• Python 3.6+ with pip

• [Strongly Recommended]: A Google Developer API Key with the 'Custom Search' API enabled. This link should take one there once logged in.

Note: While the Google tools aren't technically required for this project, much of the beneficial functionality depends on such keys/search engines. However, direct searching/parsing from a supported URL source is possible to incorporate with this package, though not the recommended way to utilize it (unless one requires a specific application requirement/design need).

The following modules will be automatically downloaded and installed as part of the standard setup:

beautifulsoup4
requests

Installation

Note that sudo may be required to install depending on your system setup. If any permission errors occur, please use the sudo flags.

This package can easily be installed with one of pip or pip3 as follows:

pip install lyricsfinder  # if pip matches Python 3.6+


pip3 install lyricsfinder # if pip3 matches Python 3.6+

Ensure your pip version matches that of Python.

Many systems will allocate pip3 to Python 3.x+, so pip3 can be used if your system has this installed. (pip will, in this case, be associated with Python 2.7.x)

Alternatively, you can install directly (ensure python3 --version is 3.6 or greater):

python3 -m pip install -U https://github.com/GieselaDev/LyricsFinder/archive/master.zip

From Source (slower/manual way):

$ git clone https://github.com/GieselaDev/LyricsFinder.git
$ cd LyricsFinder
$ python3 -m pip install .

Testing the package (optional):

You may use pytest to test the package.

Basic Usage

You can now import the package lyricsfinder as normal within your project.

import lyricsfinder

lyrics = lyricsfinder.search_lyrics("Dusk till Dawn", google_api_key="api key")

lyrics is a Lyrics instance (see below).

Expandability / Design

LyricsFinder is designed with expandability in mind. The following is a very brief structure of the project:

Source	Description
Anime Lyrics	Extractor for animelyrics.com
AZLyrics	Extractor for azlyrics.com
Genius	Extractor for genius.com
Lyricsmode	Extractor for lyricsmode.com
Lyrical Nonsense	Extractor for lyrical-nonsense.com
Musixmatch	Extractor for musixmatch.com

• Extractions can be performed directly with source URL's or with a Google Custom Search Engine which requires a Google Developer API key with the Search API enabled. This enables very accurate search results.

• Results can be stored in JSON format to cache by using json.dump on the dict that is returned by calling to_dict().

• The following contains the base model for the Lyrics Object -- within it we have our class structures for the LyricsOrigin and Lyrics classes, which we discuss below.

• The original LyricsOrigin model class contains the following attributes:

  query, url, source_name, source_url

• Similarly, the Lyrics model class contains the following attributes: title, lyrics, origin, timestamp

• The lyrics contain newline parsed lyrics, the origin contains the query which was searched for, the source_name from one of the listed sources in the above chart (such as Genius), the source_url which contains the base URL of the source, and the url contains the direct link for the track lyrics on the given source. The timestamp is a standard UNIX timestamp from the request time and the title is the parsed title of the track in question.

Please see the example of an implementation of this at the bottom of this README.

Implementations

Some current implementations:

• Giesela -- a unique music suite and player for Discord.

• GiTils -- the official utilities package for Giesela, which includes an API implementation using Flask, uWSGI served through an optimized nginx webserver. The GiTils lyrics are stored in MongoDB cache. The example can be seen here.

An example of the live implementation of GiTils' lyrics blueprint from the source in action: https://gitils.giesela.io/lyrics/substance%20therapy

Lyrics are cached in MongoDB for faster loading in this implementation.

[IMPORTANT] Please note that the above live example is not for large-scale use; the public API is monitored and rate limited to prevent abuse. If you wish to host your own version, the GiTils package linked above is the implementation of the API (along with other utilities).
