 Ohrwurm is a user-friendly bot designed to play music in Discord voice chats. Once added to your server, you can request a song using the command `/play {query}`, where query can be a URL to a YouTube video or playlist, or a simple search term. The bot will fetch the song and start playing it. You can pause the music with `/pause`, resume playback with `/resume`, and stop and clear the queue with `/stop`. If the bot is alone in a voice chat, it will automatically leave, but you can also manually make it leave with the `/leave` command.
