Stop being such a link whore, alex.
Back on topic, my latest must-have is Subsonic, which is like AudioGalaxy only way, way better. It pre-caches songs for fewer, if any skips, loads my library a lot faster and is much more stable. For example, I tried to make the same playlist of about 3,500 songs in both AudioGalaxy and Subsonic. AudioGalaxy choked and lost my entire list three times, while Subsonic hasn't had a problem with it.
