Build a music organizer

Building a music organizer involves creating a system or application that helps users manage, categorize, and access their music collection efficiently. Here’s a detailed, step-by-step guide to build a basic music organizer with features like importing music files, tagging, sorting, searching, and playlist management. This example will focus on a desktop application concept, but the principles apply to web or mobile apps as well.

Key Features of a Music Organizer

• Import music files: Scan local directories to import music.

• Metadata extraction: Read song details like title, artist, album, genre.

• Tagging and editing: Allow users to add or edit tags.

• Sorting and filtering: Sort by artist, album, genre, year, etc.

• Search: Quick search through the music library.

• Playlist management: Create, edit, and save playlists.

• Playback control (optional): Play songs directly from the organizer.

Step 1: Define the Data Structure

Each music file can be represented as an object with these attributes:

python
CopyEdit
class Song:
    def __init__(self, file_path, title, artist, album, genre, year, duration):
        self.file_path = file_path
        self.title = title
        self.artist = artist
        self.album = album
        self.genre = genre
        self.year = year
        self.duration = duration
        self.tags = []

---

Step 2: Importing Music Files and Metadata Extraction

Use a library like mutagen in Python to extract metadata from audio files (MP3, FLAC, etc.).

python
CopyEdit
from mutagen import File
import os

def scan_music_folder(folder_path):
    songs = []
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            if file.endswith(('.mp3', '.flac', '.wav', '.m4a')):
                full_path = os.path.join(root, file)
                audio = File(full_path)
                title = audio.tags.get('TIT2', 'Unknown Title') if audio.tags else 'Unknown Title'
                artist = audio.tags.get('TPE1', 'Unknown Artist') if audio.tags else 'Unknown Artist'
                album = audio.tags.get('TALB', 'Unknown Album') if audio.tags else 'Unknown Album'
                genre = audio.tags.get('TCON', 'Unknown Genre') if audio.tags else 'Unknown Genre'
                year = audio.tags.get('TDRC', 'Unknown Year') if audio.tags else 'Unknown Year'
                duration = int(audio.info.length) if audio.info else 0

                song = Song(full_path, str(title), str(artist), str(album), str(genre), str(year), duration)
                songs.append(song)
    return songs

Step 3: Organize Songs into Categories

Create structures for sorting and filtering:

python
CopyEdit
from collections import defaultdict

def organize_songs(songs):
    by_artist = defaultdict(list)
    by_album = defaultdict(list)
    by_genre = defaultdict(list)

    for song in songs:
        by_artist[song.artist].append(song)
        by_album[song.album].append(song)
        by_genre[song.genre].append(song)

    return by_artist, by_album, by_genre

---

Step 4: Implement Search Functionality

Search through the song list by title, artist, or album keywords:

python
CopyEdit
def search_songs(songs, query):
    query = query.lower()
    result = [song for song in songs if
              query in song.title.lower() or
              query in song.artist.lower() or
              query in song.album.lower()]
    return result

---

Step 5: Playlist Management

Allow users to create playlists by storing song references:

python
CopyEdit
class Playlist:
    def __init__(self, name):
        self.name = name
        self.songs = []

    def add_song(self, song):
        if song not in self.songs:
            self.songs.append(song)

    def remove_song(self, song):
        if song in self.songs:
            self.songs.remove(song)

    def list_songs(self):
        return self.songs

---

Step 6: User Interface (Optional)

A simple command-line interface or a GUI using frameworks like Tkinter, PyQt, or web frontend (React, Vue) can be created to interact with the organizer.

Example CLI snippet:

python
CopyEdit
def main():
    folder = input("Enter your music folder path: ")
    songs = scan_music_folder(folder)
    print(f"Imported {len(songs)} songs.")

    while True:
        command = input("Enter command (search, list, exit): ").lower()
        if command == 'search':
            query = input("Search for: ")
            results = search_songs(songs, query)
            for idx, song in enumerate(results, 1):
                print(f"{idx}. {song.title} by {song.artist}")
        elif command == 'list':
            for idx, song in enumerate(songs, 1):
                print(f"{idx}. {song.title} by {song.artist}")
        elif command == 'exit':
            break
        else:
            print("Unknown command")

---

Additional Enhancements

• Save playlists and music library state to disk (JSON or database).

• Edit song tags and update files.

• Integrate music playback with libraries like pygame or system media players.

• Support cover art display.

• Add duplicate detection and cleanup.

• Sync with online services or metadata databases.

This foundation provides a fully functional music organizer that can be expanded based on specific user needs or platform targets. Would you like me to provide a ready-to-run script or focus on a particular platform or feature?
