Quodlibet
Quod Libet is a GTK+ based audio player written in Python. Compared to other players, Quod Libet places a special focus on tagging capabilities and scalability to very large music collections. Its well-documented development processes have helped it accumulate a large pool of active contributors. The software is feature-rich, and has a flourishing plugin ecosystem.
This is made possible by the well-thought-out, modular structure of the project. Python is often relegated to smaller projects and simple scripts, but Quod Libet is a good demonstration of how the language can be applied to build larger programs without sacrificing usability and performance.

Quod Libet: Scalability
Introduction Scalability is an important quality attribute for many software projects, sometimes it can even be a direct prerequisite for success. With this in mind, what does scalability mean for the Quod Libet project?
Unlike some, Quod Libet will scale to libraries with tens of thousands of songs. 1
Quod Libet markets itself on its scalability, specifically promoting its suitability for massive music collections. It makes sense for us to evaluate Quod Libet’s scalability along the same axis it evaluates itself, so this article will focus primarily on how the program scales to very large music collections.

Quod Libet: Product Vision & Problem Analysis
Introduction The Quod Libet project aims to create an audio player that puts users in control of how their content is organized 1. The project is built in Python and based on the Mutagen music tagging library 2. It places a special focus on being feature-rich and customizable through plugins, and has an architecture which is designed to scale to extremely large music libraries.
