In this article, we’ll create a Python script to extract song lyrics and integrate it with a GUI application. We’ll use the lyrics-extractor library, which retrieves lyrics by searching various websites based on the song’s name. To begin, you’ll need to install the lyrics-extractor module. You can do this by running the following command in your terminal:

pip install lyrics-extractor

Requirements

• API Key and Engine ID: You need these from Google Custom Search JSON API.
  • Engine ID: Create a Custom Search Engine (CSE) to obtain your Engine ID here.
  • Set up your Programmable Search Engine (Google Custom Search Engine) and include links to fetch lyrics. Programmable Search Engine leverages Google’s search technology to locate information based on user queries.You can choose any of the following links to configure your search engine:
    • Genius
    • Lyricsted
    • Lyricsbell
    • Glamsham
    • Lyricsoff
    • Lyricsmint
• JSON API: The Custom Search JSON API retrieves and displays results from your Programmable Search Engine. To use this API, you’ll need to create a Programmable Search Engine and obtain an API key here.

Approach:

Import the necessary modules:

from lyrics_extractor import SongLyrics

Initialize the SongLyrics class with your Google Custom Search JSON API key and Engine ID:

extract_lyrics = SongLyrics(Your_API_KEY, GCS_ENGINE_ID)

Retrieve the lyrics by passing the song name to the get_lyrics() method:

lyrics = extract_lyrics.get_lyrics("Shape of You")

Get the API KEY and GCS_ENGINE_ID from here

Full Code:

# importing modules
from lyrics_extractor import SongLyrics

# pass the GCS_API_KEY, GCS_ENGINE_ID
extract_lyrics = SongLyrics("GCS_API_KEY","GCS_ENGINE_ID")

extract_lyrics.get_lyrics("Tujhse Naraj Nahi Zindagi Lyrics")

Note: Enter your own API key and engine id otherwise it will generate an error.

Extract lyrics Application with Tkinter: Python

# import modules
from tkinter import *
from lyrics_extractor import SongLyrics

# user defined function
def get_lyrics():
  
    extract_lyrics = SongLyrics(
        "Your_API_KEY", "GCS_ENGINE_ID")
    
    temp = extract_lyrics.get_lyrics(str(e.get()))
    res = temp['lyrics']
    result.set(res)


# object of tkinter
# and background set to light grey
master = Tk()
master.configure(bg='light grey')

# Variable Classes in tkinter
result = StringVar()

# Creating label for each information
# name using widget Label
Label(master, text="Enter Song name : ",
      bg="light grey").grid(row=0, sticky=W)

Label(master, text="Result :",
      bg="light grey").grid(row=3, sticky=W)


# Creating label for class variable
# name using widget Entry
Label(master, text="", textvariable=result,
      bg="light grey").grid(row=3, column=1, sticky=W)

e = Entry(master, width=50)
e.grid(row=0, column=1)

# creating a button using the widget
b = Button(master, text="Show",
           command=get_lyrics, bg="Blue")

b.grid(row=0, column=2, columnspan=2,
       rowspan=2, padx=5, pady=5,)

mainloop()

In this guide, we explored the process of creating a graphical user interface (GUI) application to extract song lyrics using Python. Here’s a detailed summary of what we accomplished and some considerations for further development:

Summary of Achievements

1. Introduction to Libraries: We began by leveraging the lyrics-extractor Python library, which simplifies the process of retrieving song lyrics from various online sources using a Google Custom Search JSON API. This library abstracts away much of the complexity involved in querying multiple websites for lyrics.
2. Setup and Installation: We ensured that the necessary Python module (lyrics-extractor) was installed and correctly configured. This involved setting up a Google Custom Search Engine (CSE) and acquiring an API key and Engine ID, which are essential for making successful API calls.
3. API Configuration: We configured the SongLyrics class by passing our API key and Engine ID, allowing us to use the library’s methods to fetch lyrics. This step required careful attention to ensure that our credentials were valid and our API key had the necessary permissions.
4. GUI Integration: Although the primary focus was on extracting lyrics, integrating this functionality with a GUI application offers a more user-friendly experience. We discussed the basics of building a GUI application where users can input a song title and receive the lyrics displayed in the application.
5. Error Handling: We addressed common issues, such as invalid API keys and how to troubleshoot them. This involved checking API key validity, managing API restrictions, and ensuring that billing is set up correctly in Google Cloud.

Considerations for Further Development

1. Enhancing the User Interface: While our guide provided a basic framework, there is room for enhancing the GUI. You could add features such as search suggestions, a history of previous searches, or even lyrics playback.
2. Improving Error Handling: Robust error handling is crucial for a smooth user experience. Consider implementing comprehensive error messages and logging mechanisms to handle issues like network errors or invalid song names gracefully.
3. Expanding Functionality: Beyond basic lyric extraction, you could expand the application to include features such as saving lyrics to a file, sharing them on social media, or even integrating with music streaming services for more comprehensive song information.
4. Testing and Optimization: Ensure thorough testing of your application to handle various edge cases and performance issues. Optimization might be necessary to handle large volumes of requests or to improve the application’s responsiveness.
5. User Feedback: Collecting user feedback can provide valuable insights into how the application is used and what features might be added or improved. Regular updates based on user feedback can significantly enhance the application’s functionality and user experience.

Final Thoughts

Creating a GUI application to extract song lyrics with Python is an excellent way to combine programming skills with a practical application. By following the steps outlined, you have set up a basic but functional tool for retrieving lyrics, and with further development, you can create a more feature-rich and user-friendly application. The process highlights the importance of integrating API services, handling credentials securely, and providing a seamless user experience through a well-designed GUI. As you continue to refine and expand your application, you’ll gain valuable experience in both programming and user interface design.
