Hey,
I'm not sure if this is the right forum, but if you're looking for a powerful music manager for MP3, OGG, and other file types that scales to 50,000+ tracks, a new release of MediaMonkey is available.
If you haven't heard of MediaMonkey, it is kind of like iTunes, but more lightweight and yet not as dumbed down--i.e. it gives you a bit more control. It tags, it rips, it plays, it synchs (with iPods and other devices), it looks up metadata, etc.
If you want to learn more, check out
