Yea, It's Audion. I never heard of it before they released it for free. I tend to like it because its small and looks nice. It also uses less processor power than iTunes, but I don't care much on my G5. I don't have much music in AAC/MP4 so it still works and it can use playlists from an iPod. It also works great with net radio. I have nothing against iTunes, but having this as a startup item is better than opening a full window in iTunes.
