filtered = pomice.TrackFilter.by_author(tracks, "Artist")

Basic Usage Example

import pomice
from discord.ext import commands

class Music(commands.Cog):
    def __init__(self, bot):
        self.bot = bot
        self.history = pomice.TrackHistory(max_size=100)
    
    @commands.Cog.listener()
    async def on_pomice_track_end(self, player, track, _):
        # Add to history when track ends
        self.history.add(track)
    
    @commands.command()
    async def stats(self, ctx):
        """Show queue statistics."""
        stats = pomice.QueueStats(ctx.voice_client.queue)
        summary = stats.get_summary()
        
        await ctx.send(
            f"**Queue Stats**\n"
            f"📊 Tracks: {summary['total_tracks']}\n"
            f"⏱️ Duration: {summary['total_duration_formatted']}\n"
            f"📡 Streams: {summary['stream_count']}\n"
            f"👥 Unique Requesters: {summary['unique_requesters']}"
        )
    
    @commands.command()
    async def history(self, ctx, limit: int = 10):
        """Show recently played tracks."""
        recent = self.history.get_last(limit)
        
        tracks_list = '\n'.join(
            f"{i}. {track.title} by {track.author}"
            for i, track in enumerate(recent, 1)
        )
        
        await ctx.send(f"**Recently Played:**\n{tracks_list}")
    
    @commands.command()
    async def export(self, ctx):
        """Export current queue."""
        pomice.PlaylistManager.export_queue(
            ctx.voice_client.queue,
            f'playlists/{ctx.guild.id}.json',
            name=f"{ctx.guild.name}'s Queue"
